Description

Incoming threat protection system and how to use it

The present invention relates to threat protection, in particular to neutralize an incoming aerial or ground threat or to reduce or prevent damage caused directly or indirectly from an incoming threat (eg missiles, or drones). A system and method for providing active protection using a UAV, eg, a drone.

Drones, which represent them as unmanned aerial vehicles (UAVs), are widely used for both civil and military purposes. Civilian uses of drones are generally for recreational purposes, commercial uses (e.g. product supply), surveillance (e.g. aerial photography), and agriculture (e.g. field fertilization). Military uses of drones generally relate to surveillance (eg signal intelligence gathering), reconnaissance (eg aerial photography), and combat/attack. Combat drones typically carry ordnance such as missiles and/or bombs and are used to strike targets. Additionally, a combat drone may have a payload, for example a supply for a pre-determined mission. Combat drones are typically under real-time human control and have varying degrees of autonomy.

Drones can have foldable wings that can be useful for saving storage space, facilitating their transportation, or for other purposes. A drone typically includes a power source (eg battery, engine), a propulsion system, and a flight control system; It may also include a navigation system. The drone may be installed with a communication device, dedicated software, for example, real-time software that enables remote control to operate all or part of the systems installed in the drone. The software can control the drone's speed and direction, take-off and landing, and more. Remote control may be for all or some of the devices/systems carried by the drone (eg operating surveillance cameras, launching missiles).

Launching a drone may require a relatively short runway, depending on factors such as drone acceleration, aerodynamics, body weight, payload, and weather conditions. Alternatively, runways or large open spaces may not be required for quadcopter-type drones, and drones that include suitable rotors. Small and/or lightweight drones can be propelled/launched by hand (thrown) or launched with a hand-held launch device, while larger drones require a platform-based launcher (eg a rail launcher). One type of launcher may be a catapult launcher, which may be pneumatic, hydraulic, or another type to elevate the drone and provide sufficient speed and angle for takeoff. The drone can also be launched from a mobile vehicle, such as by positioning the drone on top of a vehicle (eg truck) in an upwardly angled, fixed cradle or launch pad that allows the drone to be released at an appropriate speed. Alternatively, drones may be launched or released from an aerial vehicle.

Missiles and projectiles are launched from a distance and can target static objects (eg military posts, parked vehicles), or moving objects (eg helicopters, mobile tanks). Such missiles and projectiles may be operated at the launch site (e.g. computerized launch controller), and/or with a self-navigation management system within the missile or projectile, and/or a remotely controlled navigation management device (manually, fully automatically, or otherwise). operating in combination) can be used to direct them to their destination.

Aerial threat alerting systems (ATAS) can detect approaching missiles or other approaching threats, and can also enact defensive counter-measures. Different ATAS types can provide multiple alerts for multiple threats, and to varying extents. One non-limiting example of an ATAS is "Trophy" (Meil Ruach) manufactured by RAFAEL, Israel. Typically, detection is performed by electro-optical missile warning sensors, or by other technologies or combinations thereof. These sensors detect the radiant energy of the missile plume, typically in the ultraviolet and infrared portions of the electromagnetic spectrum.

Responding to the threat of an incoming/approaching missile is challenging due to the difficulty in determining whether a missile has been launched and/or the short time available for recognition of an approaching missile. This situation is typically due to the remote location of the missile's launch site, the speed of the missile, as well as other distracting factors. Moreover, some missiles (eg anti-tank missiles; surface-to-air missiles; sea-to-ground missiles) do not necessarily require long-term infrastructure and/or can be launched from well camouflaged locations or locations that are difficult to locate in advance. . Alternatively, missiles may be launched from vehicles.

Thus, defending objects of interest from projectiles and missiles can be generally categorized under two different approaches: a defensive approach, and an offensive approach. A defensive approach can be passive, e.g. adding a protective layer to a potentially threatened object, or active, e.g. frequently changing the position of a threatened object and maneuvering away from its initial position. . The aggressive approach is proactive. One type of aggressive approach is to attempt to eliminate the launch device, or its operator. However, removing the missile launch device or its operator is typically only practical when the missile is directed at its target at the launch site. An alternative offensive approach is to target an approaching missile or projectile itself. The latter alternative presents the most challenging difficulties in terms of timely discovering the exact location of an approaching missile, firing a lethal weapon against the missile, and successfully eliminating the threatening missile.

The following publications, incorporated in their entirety as all of which are fully encompassed by this disclosure, are believed to represent the related art of the lot in question.

US patent US 10,486,830 (Kahlon et al.) discloses a launcher for a foldable UAV. The launcher includes a UAV launch tube and a UAV carrying case. The launcher further includes a pneumatic booster coupled to the UAV to accelerate the UAV during launch. The launcher also includes a separation mechanism that allows separation of the booster from the UAV when the UAV leaves the launcher tube and provides kinetic energy to the UAV from the pneumatic booster during the launch phase.

Korean patent KR 10-1935262 discloses a flying object and smart drone missile for close-quarter defense to minimize damage inflicted by enemy guided missiles.

Romanian patent application RO 2016 00173 discloses a method for protecting armored fighting vehicles such as tanks or armored personnel carriers against anti-tank missiles. The method includes using at least four flying explosive shields disposed inside a compartment of a turret of a tank by an armored fighting vehicle such as a tank. Each flying explosive shield is realized with the help of a drone equipped with two proximity sensors and two directed charges with high explosives and shrapnel capable of creating an explosive surface large enough to destroy an anti-tank missile. Each flying explosive shield is connected to the armored fighting vehicle by a strong and flexible cable, whereby the drone is positioned in an optimal hovering position or optimal fighting position against anti-tank missiles attacking the armored vehicle, on-board computer, and tactical It is driven and guided with the help of data received from the radar. Anti-tank missiles are detected that they can be destroyed and deflected from their initial trajectory, regardless of whether the attacks are sequential or simultaneous, or using high or low trajectories.

European patent application EP 3 306 260 discloses a method for defending against a missile threat in the form of controllable unmanned small aircraft, during which a sequence of combat actions is selected according to increasing combat severity and carried out against the missile threat. Severity is based on a specific risk level associated with a defined possible threat level resulting from a missile threat to the area to be protected and whether an uncontrolled collision of missiles within the defense area is acceptable. A system designed for defense against threatening missiles in the form of controllable unmanned small vehicles is also described.

US 20180341262 (Yeshurun) discloses a system that facilitates an active protection system comprising at least one drone in the air in the vicinity of a protected object, wherein the drone is substantially in the vicinity of the protected object prior to tracking or neutralization of the threat or , directed to its location.

US 20170261604 (Van Voorst) discloses a tracking system for tracking a target drone and providing detection and tracking information of the target drone; a control system that processes detection and tracking information and provides guidance information for intercepting a target drone; and a high performance interceptor drone controlled by supervisory autonomy, wherein supervisory autonomy is provided by processing detection and estimation information of the target drone and sending guidance information to the interceptor drone to direct the interceptor drone to the target drone.

As will be recognized by those skilled in the art, state-of-the-art technology generally provides drones with a threat alerting system, such as an aerial alerting system (ATAS), and/or external continuous guidance that provides operational tasks to the drone. ), and/or relying entirely on control systems that process detection and tracking information before neutralizing incoming threats. These systems and their modes of operation reduce the short time available to encounter and eliminate threats, increase the potential for external warning signals, and additionally communicate with control systems subject to adversarial electronic disturbances.

Thus, it is airborne independent of any ground control unit, retains the ability to neutralize a threat at any distance from its launch site, is inexpensive, simple to operate and maintain, robust, and provides increased intercept capability against threats. Or, there is a need to provide an easily operable system to eliminate terrestrial threats.

In its most general terms, the present invention provides a simple-to-operate UAV-based system for eliminating air or ground threats that is independent of any ground control unit and retains neutralization capabilities at any distance from the UAV launch site. The system enables the launch of a UAV, eg, a drone, from any ground location towards an air or ground threat, where the UAV, as detailed herein, is launched and thereafter becomes fully autonomous. In other words, once launched, the UAV determines the location of the incoming threat and determines the most efficient route to achieve early neutralization of the threat. Prior to launch, the UAV is in an inactive or dormant state either at the launcher unit or on a ground location, which may be any ground surface or surface of a ship, mobile vehicle, etc.

As will be appreciated by those skilled in the art, the present invention relates to a novel means for protection against incoming air or terrestrial threats. Accordingly, the systems and methods of the present invention may be associated with and configured for protection of a particular object or environment, or may be located at a site independent of such object or environment. In order to provide an efficient and immediate response to an incoming threat, the system need not be associated with any particular object or environment. However, in some embodiments, the methods and systems of the present invention may be adapted or configured and suitably operable to protect at least one object from incoming air or terrestrial threats. The object can be any moving or stationary object. It may be selected from military installations and military vehicles, neighborhoods, local buildings or facilities, airports, and the like. A specific example is a tank; troop transport; person; building; This includes protecting military bases or posts, trucks and automobiles as well as air vehicles (eg helicopters, airplanes), marine vehicles (eg ships, boats), or offshore drilling rigs.

Accordingly, according to such an embodiment, a method is provided for protecting at least one object from an incoming air or terrestrial threat, the method comprising:

- receiving by at least one UAV at least one alert signal generated by at least one threat alert system (TAS) in response to detection of at least one incoming air or ground threat;

- Encounter by at least one UAV at least one incoming air or ground threat and thereby protect at least one object.

Regardless of whether the purpose of the system of the present invention is to protect specific or predefined objects, or to neutralize an incoming threat in general, the system is configured to receive an indication of an incoming threat and generate an alert signal to the UAV, thereby UAVs can be launched to intercept targets. A threat alerting system (TAS) detects an approaching threat, such as a missile, hostile UAV, or hostile ground vehicle, and enacts a defensive countermeasure by warning interceptor UAVs to launch in the direction of the incoming threat. Different TAS types can provide multiple alerts for multiple threats, and to varying extents. A non-limiting example of an airborne threat warning system, ATAS, is "Trophy" (Meil Ruach) manufactured by Rafael, Israel. Typically, detection is accomplished by electro-optical missile warning sensors, or through other technologies or combinations thereof. These sensors detect the radiant energy of the missile plume, typically in the ultraviolet and infrared portions of the electromagnetic spectrum.

According to some embodiments, a method of encountering at least one incoming air or ground threat is provided, the method being: generated by at least one threat alert system (TAS) in response to detection of the at least one incoming air or ground threat. receiving at least one alert signal by at least one UAV; as a launch and flight step of at least one UAV comprising a flight control system and at least one sensor navigation unit; The flight control system includes self-adjusting and adapting capabilities; The at least one sensor navigation unit directs the flight control system of the at least one UAV towards the at least one incoming air or ground threat, the launch and flight phase of the at least one UAV, and the at least one UAV to the at least one incoming air or ground threat. Encountering an air or ground threat.

In some embodiments, TAS is ATAS, as defined.

In some specific non-limiting embodiments, the TAS alerts the UAV to activate and launch the UAV (to activate the UAV to operate its propulsion system and to activate other systems/units of the UAV for navigation, proximity detection, etc.) and an activation alert signal generation and output unit configured to transmit a signal. Thus, when the TAS detects an incoming threat via the threat identification sensor of the TAS, the output unit represents the general direction of the threat, eg position vector data of the threat relative to the object as initially detected by the sensor. It may be configured to generate and transmit to the UAV a data alert signal comprising altitude and azimuth position data of the threat representing angles α and β. Alternatively, the output unit may send a data alert signal to the UAV that includes an alert of an incoming threat while the alert signal does not indicate (e.g., the range of the threat, and/or one or two exemplary α and β). not included) includes only partial information of the position vector of the threat. Alternatively, the output unit may send a data alert signal to the UAV containing only an alert of an incoming threat with no additional data regarding the threat. Once the general, non-specific information is received by the UAV, the UAV launches in the general direction of the threat and becomes completely autonomous from that point.

An “unmanned aerial vehicle, or UAV” used in accordance with aspects of the present invention may be any UAV known in the art. However, UAVs are not missiles. UAVs are typically drones. The drone may be a multi-rotor drone, a fixed wing drone, a hybrid-wing drone or any other drone known in the art.

A UAV used according to the present invention includes a flight control system and a sensor navigation unit. An exemplary non-limiting flight control system may be “Vector” manufactured by UAV Navigation of Spain. However, any flight control system of any other type or size may also be used. According to some embodiments, the flight control system includes self-tuning and adaptive capabilities (eg artificial intelligence), which enable the UAV to fly to reach and encounter threats; Allows maneuvering and turning. A sensor navigation unit may be an optical sensor (eg electro-optical), radar, LIDAR, a combination thereof, or any other useful sensor. LIDAR is a device that uses a method for measuring distance (ranging), usually by illuminating a target with laser light and measuring the reflection with a sensor. According to some embodiments, the sensor navigation unit may be part of a flight control system.

The sensor navigation unit provides the threat's position vector to the flight control system and the UAV, and upon receiving the initial direction of the threat, the UAV self-navigates to encounter the threat. As used herein, the term “ self-navigate ” means fully autonomous Refers to the capabilities of the UAV. In other words, the UAV has full static automation, whereby the UAV makes all necessary decisions for successful mission completion. Once the UAV is launched in the general direction of an incoming threat, or once the UAV is given the initial direction of the threat, the UAV maneuvers by self-control without requiring pilot or operator intervention. Under certain circumstances, the sensor navigation unit may provide modified or updated position vectors to the UAV while in flight. However, these updated parameters do not hinder or affect the UAV's self-navigation. In other words, the self-navigating or autonomous UAV of the systems and methods of the present invention is independent of any ground control or operation.

As mentioned above, flight control systems include self-tuning and adaptive capabilities.

A UAV is said to be inactive or dormant when an alert signal is received from the TAS. In other words, at the time of receiving an alert signal, the UAV is on the ground waiting to initiate action. Accordingly, the terms “ deactivated ” or “ at rest” refer to a non-active or flight-mode of a UAV, where the UAV is either on the ground or in a launch device. The ground on which a UAV or launch device is located can be any fixed or mobile site or location, including fixed launch sites and sites established on ships and other mobile vehicles. Accordingly, launch includes launch of the UAV from its launch site or launch system.

The protection system may be implemented on a UAV where the UAV is designed or intended to encounter threats. The term “encounter” or any linguistic variation thereof, when made in reference to a UAV, generally means “come into contact” or “at a sufficiently close range” to allow neutralization of an incoming threat. or at an effective distance)". In some embodiments, a threat may be neutralized by an actual collision, ie physical contact between an air or ground threat and any section of the UAV.

Thus, encountering a UAV with a threat may be by collision, or by proximity collision, which activates (e.g. explodes) the threat's warhead, causes irreversible damage to the threat, or A threat can be diverted from reaching its destination, or its predefined lethal effects can be reduced or minimized upon reaching its destination.

To achieve effective neutralization, the UAV may further be equipped with an encountering mechanism capable of generating a shock wave to reduce or eliminate the threat. According to some embodiments, the shock wave may be generated by the UAV's payload. Accordingly, a UAV may be designed or configured (and operable) to detonate on or near contact with a threat, via an explosive payload or an explosive device, which may include any type of trigger element. The trigger element may be any type of fuse, such as a proximity fuse; It may be a contact fuse, or a combination thereof, a signal detonation activator, an airbag mechanism that triggers a detonation and/or movement of a mechanical handle, or something else. A proximity sensor can be used to trigger a blast away from a threat. Proximity sensors can be optical sensors, thermal sensors, electromagnetic sensors, RF sensors, or any other sensor that allows effective determination of proximity to a threat.

The threat to be neutralized may be an air or ground threat such as a missile, hostile UAV or drone, military vehicle, hostile vehicle, or any other air or ground vehicle requiring neutralization. In some embodiments, the threat is an airborne threat that may be intercepted during its travel through the air.

According to another aspect of the present invention, a method of protecting at least one object from at least one incoming air or ground threat is provided, the method using at least one threat alert system (TAS), such as an ATAS, to prevent at least one incoming air or ground threat. generating and transmitting at least one alert signal of an airborne or terrestrial threat; launching at least one UAV comprising at least one flight control system and at least one sensor navigation unit; launching the at least one UAV, wherein the at least one sensor navigation unit directs the at least one flight control system that navigates the at least one UAV toward the at least one incoming threat, and the at least one incoming air or ground Encountering the threat and at least one UAV.

The present invention may be more clearly understood upon reading the following detailed description of non-limiting exemplary embodiments of the present invention with reference to the following drawings, wherein:
1 is a schematic diagram of an incoming air threat protection system according to an embodiment of the present invention.
2 is a perspective view of an exemplary Unmanned Aerial Vehicle (UAV) according to an embodiment of the invention.
3 is a schematic diagram of an incoming air threat protection system according to a further embodiment of the present invention.
The following detailed description of embodiments of the present invention refers to the accompanying drawings mentioned above. Dimensions of components and features shown in the drawings are selected for convenience or clarity of presentation and are not necessarily drawn to scale. Wherever possible, the same reference numbers will be used throughout the drawings and the following description to refer to like and like parts.

Exemplary embodiments of the present invention are described below. In the interest of clarity, not necessarily all features/components of an actual implementation have been described.

1 shows an incoming air threat protection system according to the present invention for protecting an object 100 exemplified by a tank. The incoming air threat protection system includes a tank; troop transport; person; building; Protects a variety of objects that may be mobile or stationary, including but not limited to one or more of military sites or posts, trucks and automobiles, as well as air vehicles (eg helicopters, airplanes), marine vehicles (eg ships , boats), or to protect offshore drilling equipment.

Furthermore, despite the simple association shown in FIG. 1 between the object to be protected and the UAV, the UAV can be positioned independently of any one object and operated to neutralize incoming threats that are not necessarily directed at a particular object. should also be understood. Further, while the figures demonstrating the featured embodiments of the present invention contemplate protection against incoming airborne threats, similar configurations can be considered for protection against incoming terrestrial threats. Where ATAS units are concerned with detecting air threats, TAS units are concerned with detecting terrestrial threats. Accordingly, the embodiments of the present invention presented below with respect to the drawings may similarly be stated as including a TAS rather than an ATAS unit. Therefore, the reference to ATAS below is not limiting.

An incoming air threat protection system includes a UAV 20 (which may also be interchangeably referred to as a “drone” in the specification and claims herein). The protection system also includes, for example, a plume sensor that detects the radiant energy of the missile plume, typically in the ultraviolet and infrared portions of the electromagnetic spectrum (exemplified by a missile containing a warhead) from incoming air threats. and an aerial threat alerting system (ATAS) 22 having a threat identification sensor 24 configured to identify 102 . Optionally, ATAS 22 may provide alerts of the launch site of airborne threat 102. After launch, the UAV 20 flies on a flight path 23 towards the incoming air threat 102 .

As noted herein, a threat alert system (TAS) can detect approaching missiles or other approaching air or ground threats, and can also enact defensive countermeasures. Different TAS types can provide multiple alerts for multiple threats, and to varying extents. One non-limiting example of an ATAS is "Trophy" (Meil Ruach) manufactured by RAFAEL, Israel. Typically, detection is accomplished by electro-optical missile warning sensors, or through other technologies or combinations thereof. These sensors typically detect the radiant energy of the missile plume in the ultraviolet and infrared portions of the electromagnetic spectrum. Threat alert systems for incoming terrestrial threats, as disclosed herein, are similarly known.

ATAS 22 is used to activate and launch the UAV (to activate the UAV to operate its propulsion system 36 (FIG. 2) and to activate other systems/units of the UAV for navigation, proximity detection, etc.) and an activation alert signal generation and output unit 26 (hereinafter referred to as “ unit 26 ” or “ output unit 26 ”) configured to transmit a signal to the UAV 20. Accordingly, when the ATAS 22 detects an incoming airborne threat 102 via the ATAS threat identification sensor 24, the output unit 26 outputs a data alert signal containing the general direction of the airborne threat 102, e.g. Generate altitude and azimuth position data of the threat 102 representing example angles α and β representing position vector data of the air threat 102 relative to the object as initially detected by the sensor 24, e.g. (20). Alternatively, the output unit 26 may transmit a data alert signal to the UAV 20 that includes an alert signal of an incoming air threat 102 while the alert signal is (e.g., range of the air threat 102; and/or only partial information of the position vector of the air threat 102 (not representing one or two example angles α and β). Alternatively, the output unit 26 may send a data alert signal to the UAV 20 containing only an alert of an incoming air threat 102 without additional data regarding the air threat 102 .

Airborne threat 102 is illustrated and sometimes referred to as a missile, however, one skilled in the art can readily appreciate that this embodiment is non-limiting. An aerial threat may be any type of drone, or other threatening object. Threats do not have to move constantly or at all. Moreover, an airborne threat relates to any object that threatens, or may in some way threaten, an object or site by approaching a particular location of interest (eg, a tank or helicopter, an object of military importance, such as a strategic site). Access may be by air, but is not limited to movement by air, and thus access may alternatively or additionally be through another medium such as water, ground, or a combination thereof. Alternatively, a public threat may be a surveillance item that operates against its interests (eg, violating privacy by tracking and/or collecting and/or transmitting data). An airborne threat may be an object identified by ATAS as either an immediate threat (within a given short period of time), or a threat that may become operational at a later time interval after being detected by ATAS.

2 is a more detailed schematic diagram of an exemplary UAV of protection system, such as UAV 20, including flight control system 28 (located within UAV 20), and sensor navigation unit 30. show An exemplary non-limiting flight control system 28 may be “Vector” manufactured by UAV Navigation of Spain. However, any flight control system of any other type or size may also be used. According to some embodiments, the flight control system includes self-tuning and adaptive capabilities (eg artificial intelligence), which allow the UAV to fly to reach and encounter airborne threats 102; It can be maneuvered and circulated. Sensor Navigation unit 30 may be an optical sensor (eg electro-optical), radar, LIDAR, a combination thereof, or any other useful sensor. LIDAR generally refers to a device that uses a method for measuring distance (ranging) by illuminating a target with laser light and measuring the reflection with a sensor. According to some embodiments, sensor navigation unit 30 may be part of flight control system 28 .

A protection system may be implemented wherein the UAV 20 is designed/intended to encounter an airborne threat 102 . A UAV 20 that encounters an airborne threat 102 may be enabled after its launch by the flight control system 28 and the sensor navigation unit 30 that directs the UAV 20 . Accordingly, the sensor navigation unit 30 provides the position vector of the airborne threat 102 to the flight control system 28 . The UAV 20 may receive an initial direction of the air threat 102 from the output unit 26 and then self-navigate to encounter the air threat 102 . Alternatively, if the initial direction of the air threat 102 is not received from the output unit 26, and upon launch, or immediately thereafter, the UAV 20 may use the flight control system ( 28), and self-navigation using the sensor navigation unit 30.

The encountering of the UAV 20 and the air threat 102 is an actual collision between any section of the air threat 102 and the UAV 20 and/or any section of the UAV 20's encountering mechanism, i.e. refers to physical contact. Moreover, the encounter may also affect the ability of the aerial threat 102 to reach the object 100 and/or reduce the effectiveness of the aerial threat 102 with respect to the object 100. Refers to the presence of a UAV 20 in the vicinity, and/or an encounter mechanism of the UAV 20.

Thus, the encounter of the aerial threat 102 and the UAV 20 may be by collision or near collision, which may cause the aerial threat 102 to reach its destination (e.g., platform 100 in FIG. 1). can activate (e.g. explode) its warhead. Alternatively, an encounter of an airborne threat 102 and a UAV 20 diverts the airborne threat 102 from reaching its destination (e.g., platform 100 of FIG. 1), and/or may reduce the predefined lethal effect of the airborne threat 102 upon arrival.

An encounter of a UAV 20 with an air threat 102 that involves physical contact (e.g., collision), or a UAV 20 traversing in the vicinity of an air threat 102 is reached by the encounter mechanism of the UAV 20. It can be. Accordingly, according to some embodiments, the encounter mechanism may create a shock wave that may reduce or remove a threat from the platform 100 of FIG. 1 . Thus, the shock wave generated by the UAV 20 may activate the warhead of the air threat 102 and/or divert the air threat 102 from reaching its destination. According to some embodiments, the shock wave may be generated by the payload of the UAV 20 . Accordingly, the UAV 20 may be designed/intended to detonate the air threat 102 via an explosive payload or explosive device 32, which may include a trigger element such as a fuse 33. The trigger element may be any type of fuse (eg proximity fuse; contact fuse, combinations thereof), a signal detonation activator, an airbag mechanism that triggers an explosion and/or movement of a mechanical handle, and others. A triggering factor that triggers detonation of an explosive payload or explosive device 32 may result from a collision of the airborne threat 102 with the UAV 20 . Additionally or alternatively, triggering detonation of the explosive payload or explosive device 32 may be due to a proximity sensor activating a trigger element. Accordingly, the UAV 20 includes a threat proximity sensor 34, which can be an optical sensor, a thermal sensor, an electromagnetic sensor, an RF sensor, any combination thereof, or a sensor that the UAV can use to remove or reduce a threat from the object 100. It may be any other sensor that allows it to determine if/when it is in an appropriate vicinity for an aerial threat 102. Thus, if proximity sensor 34 determines that UAV 20 is within the vicinity of an encounter of airborne threat 102, sensor 34 will send an alert signal that detonates the explosive payload or explosive device 32 to the trigger element ( For example, it is generated in the fuse 33. The encounter vicinity may be predefined depending on the explosive payload or the explosive effect of the explosive device 32 (e.g., a distance of less than 10 meters, less than 25 meters, less than 50 meters, or less than 100 meters from the air threat 102). ).

Another embodiment of the present invention may provide that the sensor navigation unit 30 of the UAV 20 may also serve as a proximity sensor of the UAV 20 alternatively to, or in addition to, the proximity sensor 34. there is.

In further embodiments, the UAV 20 may additionally or alternatively include other encounter mechanisms for the explosive payload or explosive device 32 . Deploying other encounter mechanisms is not limited to the location of the explosive payload or explosive device 32, but is within the UAV 20, or any part of the UAV 20 (e.g., front, back, sides). is adjacent to Another encounter mechanism can be any mechanism that can eliminate, or at least reduce, the threat of an object (eg, object 100) when it can encounter an aerial threat (eg, aerial threat 102). there is. Examples of encounter mechanisms may include laser beam weapons, and/or firearms, or multiple thereof. Accordingly, the selective action of a laser beam weapon, or firearm, is performed by proximity sensor 34 and/or sensor navigation unit 30 (i.e., air threat 102) to identify the proximity and thereafter trigger element. may be initiated by a trigger element activated by a proximity sensor). Depending on the above encounter mechanism, and thereafter, encountering the aerial threat 102 and its warhead activated, diverting the aerial threat 102 from reaching the object 100, or diverting the aerial threat 102 from reaching the object 100, or Possible damage from threat 102 can be reduced.

According to some embodiments, proximity sensor 34, and/or sensor navigation unit 30 may include a predefined proximity range of air threat 102, where UAV 20 is at the predefined distance. A determination to be within, or below, will activate a trigger element that will initiate detonation of the explosive payload or explosive device 32 . A predefined proximity distance may be defined according to an explosive payload or explosive device and its ability to eliminate, or at least reduce, the threat of an airborne threat 102 . Similarly, a UAV 20 that includes another encounter mechanism will have a predefined proximity distance, such as less than 25 meters, less than 50 meters, less than 200 meters, or even more, depending on the capabilities of the encounter mechanism.

Additionally or alternatively, the UAV 20 may include an additional encounter mechanism, which is a net. A net may include a plurality of weights. The weights may be embedded in the net, optionally at or adjacent to the edge of the net, and/or throughout the net. The weight may be a small weight of 0.01-1.0 kilometres, or a heavier weight. Additionally or alternatively, the net may include heavier portions that are at most the edge, or close to the edge of the net. Thus, a UAV 20 that includes a proximity sensor 34 can activate the release of a net from that position held as the payload of the UAV 20 . Release of the net according to some embodiments may be by proximity sensor 34 activating a trigger element that releases the net from its position. The location of the net prior to release may be adjacent to and/or within any portion of the UAV 20 . Thus, the trigger element may simply allow release of the net from its holding position and/or stimulate release of the net in a specific direction (eg by way of a spring). The location of the net prior to release (optionally in front of, below, or above the UAV 20) is such that once released the net spreads over a large area, such that the net is perpendicular to the direction of flight of the UAV 20 after its release. It can be in one stage.

Net ejection provides a large spread of nets that may or may not be attached to the UAV 20 after ejection, thus significantly increasing the ability of an aerial threat 102 encounter, and/or close-impact collision. Thus, a net encounter may detonate the warhead of the air threat 102 (eg, by touching, striking, colliding with, or within proximity of the warhead). Spread of the net may be achieved due to the initial kinetic energy of the net at its release (ie its motion as it attaches to the UAV 20), and the mass of a weight attached to the net, or alternatively the weight of the net. Concentrating the mass on the edge (e.g., a built-in weight containing a heavier part), or concentrating the mass close to the edge, provides an initial wide spread of the net, and after impact of the net, or part thereof, It may also provide the aerial threat 102 with a wrapping movement of the net, or portion thereof, around at least a portion of the aerial threat 102 .

According to some embodiments, the UAV 20 may include more than one net, while in other embodiments the ejection of the nets and subsequent spreading thereof may leave portions of the nets attached to the UAV 20. may include that there is The part attached to the UAV 20 may be a part or parts of the net itself. Additionally or alternatively, the net may remain attached to the UAV 20 using a cord, or cords, so that, optionally, the net may be deployed some distance away from the UAV 20 (e.g. , partially open, fully open) (e.g., avoid/minimize touch of the net with the rotor or other parts of the UAV 20). The area of the net ranges from 0.5 m ² to It can be of different sizes up to 100 m ² . According to some embodiments, immediately after the net is released, the UAV 20 tours or stops its propulsion means (eg, stops the engine of the UAV 20) and does not continue its flight. According to some embodiments, proximity sensor 34 , and/or sensor navigation unit 30 can detect a distance of less than 5 meters, less than 10 meters, less than 20 meters, less than 50 meters, or less than 100 meters from air threat 102 . You can activate net release from

Additional encounter mechanisms may include radar jamming devices and/or deception devices that are activated to encounter airborne threat 102 and thus reduce its ability to attack object 100 . The radar jamming device and/or deception device may be based on electronic jamming (eg, using an electronic jamming device), and/or optical deception (eg, using an optical deception device), or other means. The radar jamming device and/or the optical decoy device is activated immediately after launch of the UAV 20, or after being triggered by a trigger element activated by the proximity sensor 34 (e.g. air threat 102, launch of the air threat). position) can be activated. Accordingly, proximity sensor 34 may initiate electronic jamming and/or optical deception directly by generating a signal that is received by the electronic jamming device and/or the optical deception device, respectively. Alternatively, electronic jamming and/or optical deception may be initiated after proximity sensor 34 activates a trigger element that initiates the electronic jamming and/or optical deception. According to some embodiments, proximity sensor 34, and/or sensor navigation unit 30 can detect airborne threats 102 less than 15 meters, less than 30 meters, less than 50 meters, less than 150 meters, less than 500 meters, less than 1.0 kilometer. and/or activating the jamming device and/or the optical decoying device at a distance of less than, less than 2.0 kilometers, or more.

According to some embodiments, the sensor navigation unit 30 may include a radar, for example a long-range radar (LRR) system. According to some embodiments, the LRR may use the 77 GHz band (in the range of 76-81 GHz), or the 33 GHz band to provide better accuracy and better resolution in a smaller package. Further embodiments may use any range of 1-100 GHz. LRR can also be used to measure distance and speed to an airborne threat 102 in a wide field of view for, for example, a cross-traffic alert system. One non-limiting example radar is Banner Engineering Corp. U.S.A. etc., which can be adjusted to a longer range. Thus, long-range applications require directional antennas that provide higher resolution within a more limited scanning range. The LRR system provides an identification range starting a few meters from the location of the LRR, reaching 1,000 m, and alternatively extending the range to 2,000, 3,000 m, 5-20 Km, or even more.

The UAV 20 includes a propulsion system 36 (eg, a battery or battery system, or an engine, or other suitable means of propulsion). If an engine, it may be of the jet engine type or used to power one or more rotors 37 to provide lift and forward motion as required.

The UAV 20 typically also includes wings 40, which are deformable, and thus may be configured to fold per se by any known mechanism, whereby the UAV may be configured to move through a launch tube It can be fitted in or, if there is one, simply more convenient for more convenient transportation and storage. Alternatively, the UAVs used in accordance with the present invention may have single wings or no wings at all (eg rotor UAVs) and thus may be equipped with other means of turning, or a combination thereof. The UAV 20 may also include a stabilizer 42 having one or more tail rudder.

2 shows one type of UAV, it will be clear to those skilled in the art that the UAV 20 can be any other type of UAV. For example, multi-rotor UAVs, single-wing UAVs, single-rotor helicopters, quadcopters, VTOL (vertical take-off and landing) UAVs, and others are each within the scope of demonstrating the present invention, and all shown from the perspective of the UAV 20 elements may be included. Moreover, the UAV 20, as well as other UAVs that may be used in accordance with the present invention, may place one or more of the elements shown in different parts of the UAV, and/or different configurations. In other embodiments, the UAV of the present invention may include additional elements, or alternatively fewer of the elements shown from the perspective of the UAV 20 . In other embodiments, deformable UAVs may have other foldable, and/or bendable portions that are configured to be folded and/or bent by any mechanism or due to their structure (e.g., construction materials, assembly of parts). This may allow the UAV to be fitted into a launch tube or mechanism, or, if any, simply allow for more convenient transport and storage. Providing an exemplary non-limiting deformable UAV may be a UAV that includes a folding rotor, or a folding quadcopter.

1 and 3 show an airborne threat 102 such as a missile containing a warhead. However, the examples should be regarded as non-limiting examples. Accordingly, embodiments of the present method and system are configured to address all airborne threats. Thus, additional exemplary aerial threats may be UAVs, projectiles, and aircraft from any type. Moreover, the shape and size of the air threat is also not limited.

3 shows a further embodiment of the present invention wherein the protection system further comprises two UAVs 20; 21, and a launch mechanism 38 (exemplified by a launch tube) for launching the UAVs 20 . ATAS 22, and output unit 26 can activate the launch of UAVs 20 and 21. Operation of UAV 20 and UAV 21 may be simultaneous or sequential. The launch mechanism 38 may also be activated by the output unit 26 to activate the launch UAV 20 . Alternatively, the output unit 26 may activate the firing mechanism 38 and the UAV 20 simultaneously or sequentially. Firing mechanism 38 is via a rotatable and/or tiltable base 44 to direct the launch of UAV 20 in the general direction of threat 102 (e.g. a base for directing a tank's cannon and similarly). Directing the firing mechanism 38 in the desired direction (ie, the direction of the air threat 102) may be passive. Alternatively, base 44 may be rotated and/or tilted after being activated by output unit 26 . Accordingly, after base 44 receives an alert signal (e.g., including position vector data of air threat 102, or partial position vector data thereof) from output unit 26, base 44 Rotates and/or tilts the firing mechanism 38, thus directing the firing mechanism 38 towards an approaching, or threatening, air threat 102. Additionally or alternatively, base 44 may be rotated and/or tilted mechanically rather than in direct response to an alert signal from output unit 26 . Firing mechanism 38 may be a pyrotechnic firing mechanism. Alternatively, firing mechanism 38 may be a compressed gas firing mechanism. Optionally, firing mechanism 38 may be a mechanical firing mechanism, for example comprising a spring.

In some implementations, the UAV 20 may be turning prior to receiving any alert signals from the ATAS 22. According to the implementation, launch of the UAV 20 towards the air threat 102 may occur after receiving an alert signal from the ATAS 22 .

According to a further embodiment of the present invention, the air threat protection system may include, in addition to the ATAS 22, one drone 20, two drones, or more drones, wherein one or more of the drones are protected It may be mounted on or near the object to be (eg, the object 100). The vicinity of the object to be protected may be, for example, at a distance of less than 10 meters, less than 50 meters, less than 100 meters, less than 500 meters, less than 1.0 km, less than 15.0 km from the object to be protected. Additional embodiments may provide that within one airborne protection system there are different types of drones that may use alternative launch mechanisms and/or may not use launch mechanisms. One exemplary launch mechanism generally relates to a mechanism comprising a tube wherein a folded quadcopter can be inserted prior to launch, and after receiving an alert signal from ATAS, the quadcopter is actuated and launched from the launch mechanism and another In an embodiment the quadcopter may be launched first and activated later. After leaving the launch mechanism, the quadcopter deploys and flies toward the air threat for an encounter with the air threat.

Other embodiments of the present invention may include a UAV, or UAVs that protect a single object, or more than one object, where the airborne threat protection system includes no launch mechanism, one or more launch mechanisms, or no launch mechanism at all. may not include

Embodiments of the present invention comprising more than one drone, a single ATAS 22, or multiple ATAS 22 may be used to activate the drone (one or more drones). Thus, a system comprising more than one drone provides that a drone may be simultaneously or sequentially activated by the ATAS or ATAS to approach the threat 102 . The ATAS may be mounted on the object 100 or at a location away from the object 100 . Alternatively, ATAS 22 may be located in the vicinity of object 100, for example less than 10 meters, less than 50 meters, less than 100 meters, less than 500 meters, less than 1.0 Km, less than 1.0 Km from object 100, It can be less than 5.0 Km away.

Moreover, in embodiments according to the invention comprising more than one drone, the protection system may comprise an additional drone launch control unit. The drone launch control unit may receive an alert signal from the output unit 26 of the ATAS 22 (and/or the plurality of ATAS 22). The drone launch control unit may activate one or more drones towards one approaching threat 102 and not activate one or more other drones of the protection system. Alternatively, the drone launch control unit may select one or more drones to be activated for an approaching threat and activate one or more other drones for one or more additional selected threats.

Other embodiments of the invention may provide the UAV 10 to receive more than one alert signal regarding one or more airborne threats approaching the object to be protected.

According to another embodiment, the air threat protection system may additionally or alternatively include a drone that also includes an ATAS. Thus, in this embodiment, the ATAS included in the drone 20 includes an identification sensor and an output unit similar to that of the ATAS 22 (i.e. similar to the sensor 24 and the output unit 26). can do. As a result, the drone 20 does not depend on the presence of an ATAS mounted on and/or in the vicinity of the object to be protected. An ATAS 22 mounted on the drone 20 may generate an alert signal, which may activate the drone and it is in a state to fly toward the approaching threat 102 . A further embodiment provides an ATAS 22 mounted on a drone, wherein the output unit 26 has a rotatable and/or tiltable base 44, and/or a launch mechanism 38 (from the perspective of FIG. 3 shown), and the drone itself.
