Description

Protection device for a land area Against enemy threats.

The present invention relates to a protection device for a land area against threats Enemies

The protection of a land area against any enemy threat may include protection levels following: prohibition to penetrate this area, deterrence of attempted intrusion and treatment of threats represented for armed elements that have been able to penetrate the area.

Known protection systems include essentially conventional minefields (buried or scattered) or weapons whose field of action covers this area, (weapons called "WAM"). These systems integrate in the same set Threat detection and protection reaction. The media of detection and protection used are adapted to a single type of intruders. The reaction is triggered automatically within a predetermined delay time from the detection of the threat, which implies the almost systematic destruction of detection sensors and thus generates a gap in the system zone protection. There is no possible action of man to judge about the need and the nature of the reaction. In addition, in the end of a mission the recurring problem of the "decontamination" of the land if there has been no reaction (withdrawal from the mines).

It is known by document DE-40 29 898 a protection device for a tension zone in which the ground bases include acoustic or laser sensors that, by they alone cannot ensure a precise location of the intruders in the protected area, particularly if these intruders do not they are visible in direct mink; This document covers the characteristics of the preamble of claim 1.

It is known by the document DE-A-41 33 543 a mine that includes an acoustic sensor that puts the mine in a waking state when an acoustic signal from a helicopter is detected. In this waking state an NLOS radar, which is an integral part of the mine, it carries out measures to detect the radial velocity and the Distance from an enemy helicopter. When the result of these measures shows that the enemy helicopter is located in the mine radius, this mine is activated.

It is known by the documents WO-A-01/33253 and WO-A-01/46010 a system of zone protection that avoids the use of mines, including this system a detection device and weapons teleoperated, but whose captors cannot ensure a precise location of intruders.

The present invention aims at a effective protection device for a land area against enemy threats, allowing precise location of intruders in the protected area, even if these are not visible in direct vision, that has an autonomous operation, conserving the own time the possibility of man validating a reaction global or partial, that is hardly detectable, that does not expose the  personnel for its use, being able to control and adapt to own time the nature of the reaction depending on the operational situation, which is compatible with the systems of battlefield information and with devices Friend / Enemy Identification (IFF), whose use is very fast, need few human resources for its deployment and management, which can be quickly removed without letting a danger subsist remaining in the protected area at the end of a mission (of compliance with the Ottawa agreements), and that it can deal with aggressions of all types of land vehicles (armored heavy, light, unarmored vehicles, ...), as well as protect areas against infantrymen, and this at the lowest cost.

The device according to the invention comprises three main subsets linked together by a network of telecommunications, these three subsets being: a position of remote control of the area, a detection device and location of intrusion arranged in the area or in its vicinity, and teleoperated weapons, comprising the detection device and of location several "ground bases" that include each of they are a computer, a transmitter-receiver and sensors, and is characterized by the fact that these sensors include the minus an NLOS radar in UHF / VHF and an acoustic sensor, whose information is merged and weighted by the computer, being teleoperated weapons arranged outside the area in such a way that at least one of them can reach any point of the zone.

The invention will be better understood by reading of the detailed description of an embodiment, taken from non-limiting example title and illustrated by the attached drawing, in which:

Figure 9 is a schematic of a variant of embodiment of the device of figure 2 with a view to protection  of a site without invading this site.

In the scheme of figure 1 it has been represented the block diagram of the essential constituents of zone protection device 1 of the invention. This device includes: a set α of M "bases of soil "2.1 to 2.M distributed throughout the area to be protected and / or in the proximity of this area, several (N) weapons or 3 sets of weapons teleoperated 3.1 to 3.N, and a command post (PC) 4 attached to the ground bases and teleoperated weapons (preferably link radio), as well as at a higher level of command 5 via a network 6.

In general, the ground bases are In charge of intrusion detection, location and their classification (small or large groups of soldiers of infantry, light or heavy land vehicles, aircraft, ...) If these intrusions persist, teleoperated weapons are responsible for treating them (deterrence, partial or total destruction, ...) Command post 4 centrally manages all These operations.

In figure 2 it has been represented in a way simplified an example of device placement of the invention. The zone 7 to be protected is in this example of form rectangular. There are 7 ground bases in this area, referenced 2.1 to 2.6, so that circular surfaces corresponding to their respective radios of action cover almost completely the surface of zone 7. The radios of action are defined as the maximum distance at which qualities of detection, location and classification of ground bases are equal to a given threshold (for which they are acceptable these qualities).

Teleoperated weapons 3.1, 3.2, ... are arranged outside of zone 7 such that at least one of between them can reach any point in zone 7. These weapons they can be shot or curved, they can make shots of blinding, lighting, neutralization or destruction, and can be concealed in front of people or detection devices that are in zone 7 or in the vicinity of it. For example, these weapons may be hidden by a terrain relief or by natural obstacles or constructions.

The amount of ground bases and weapons necessary teleoperations to ensure the protection of a given area  and their respective locations are determined by the post of command 4, which has the appropriate computer equipment.

The ground bases are programmed during their placement and deposited manually (by a tour operator a predetermined circuit in vehicle or on foot) or automatically (for example, by telecommanded vehicles, or launched at altitude from rockets, aircraft, helicopters, ...)

Teleoperated weapons can be deployed towing them by a light vehicle, transporting them in helicopter directly to the designated position or driving them to your site (by an operator or by remote control), if They are automotive.

Command post 4 chooses the strategy of defense (automatic, manual, deterrence, coercion, ...) and can modify it in real time depending on the conditions of the intrusions (change of the nature of the intrusions and / or their importance, persistent or momentary intrusions, ...). The post 4 can also activate the wake mode of a part or of the all floor bases either disable this mode or modify the number of ground bases under vigil. Ground bases they can also communicate with each other, for example to relieve to those that are too far away from PC 4, or (figure 3) when one of them has just detected an intrusion 8, in order of pointing it to neighboring bases and communicating at least approximately the characteristics of this intrusion (see the Figure 4) (direction of travel, location, nature, importance, ...), for example to deactivate your waking state, to allow them, if necessary, to better target their collectors or to carry out precise location measurements with them triangulation Of course, these communications are supervised. by the command post, which may eventually intervene to modify or complete them (for example, if they had been indicated other intrusions at another end of the protected area or if receive other information not accessible to the ground bases, for example information from satellites or airplanes of recognition or information network and command 5, figure 1). Advantageously, soil bases dedicated to detection advanced (not shown) may be placed upstream of The area to protect.

Command post 4 includes, among others, a computer that receives information from the various device floor bases, allowing you to update on real time the operational situation of the protected area, in particular to take into account intrusions detected by the bases of soil. From this information, determine a scenario of reaction to these intrusions. If the automatic reaction mode is not validated, the PC 4 operators determine, in conjunction with the upper level of command, the reaction scenario. This scenario it can be the one proposed by the computer or a variant of it, whose parameters are modified by the operators. In case on the contrary, the computer applies the reaction scenario that has elaborated, teleoperating weapons 3.1, 3.2, ... that you have selected (figure 5) the teleoperation of weapons can also be left to the initiative of the PC operators 4. These operators or the Computer can teleoperate weapons for other missions. At the end of the intervention, the PC sends a report to the top level of command. All floor bases, or a part thereof, can be laid then on watch or deactivated by remote control from the PC. At the end of the mission (determined by the PC or its higher level of command), that is, when there is no longer any danger to the area protected, the PC and teleoperated weapons are repatriated. In function of the accessibility of the protected area, the ground bases They can be recovered, sterilized or self-destroyed.

As schematically shown in Figure 6A, a floor base 2.k (one of the set 2) comprises a support part 9 that encloses a power source that feeds its other components, a computer 10, a radio transmitter-receiver , preferably with encryption, a radar detector 12 that works, for example, in the UHF band, and sensors 13 that can include different kinds of sensors (acoustic, seismic, magnetic, optical, ...) and, advantageously , a GPS tracking device referenced with 14. The nature of the sensors will be adapted according to the nature of the intrusion (vehicle, infantryman, aero
ship, ...) that you want to deal with.

The example of the floor base illustrated in the Figure 6B prefigures a launchable equipment dedicated to the detection of vehicle intrusion. As depicted in Figure 6B, the part support 9 of the floor base 2.k can have a shape cylindrical, of the upper face from which the antennas of Radar referenced with 15 as a whole and 16 microphones Acoustic sensors This support part 9 rests on a 17 inflatable cushion that allows you to launch the floor base from an airplane or a helicopter, allowing it to land without damage, and also stabilize in the desired position.

The operating modes of the bases of ground are, for example, the following: a mode of suspension, a wake mode, location mode and evaluation mode. In The sleep mode is not active in any of its sensors. In the wake mode is only activated the acoustic detection (microphones 16), which allows to detect most of the intrusions The location mode, automatically activated as consequence of the detection of an intrusion or by remote control, allows to determine the position of the intruder. In the mode of base evaluation assesses the importance of the impacts of ammunition of teleoperated weapons and the resulting destruction from them.

The ground bases are able to detect, classify (at least approximately) and locate the intruder, even in the absence of intervisibility with it.

These functions are obtained thanks to the association of two categories of detection procedures, particularly effective against land vehicles in situation NLOS (Non Line Of Sight = not in direct vision), contributing from decisive way the NLOS capabilities of the bases to improve its ability to survive despite the presence of intruders. These detection procedures use a network of sensors acoustics that ensures surveillance functions and that contributes to the detection of intruders and their classification, and a network of NLOS radar in VHF / UHF band that ensures the functions of detection confirmation, precise location and tracking of intruders These sensors are connected to a computer (10) that Treat your output signals. This computer merges the information issued by these two networks and weights them so that the following aspects, appropriate for detection, be addressed in autonomous mode, in a situation of multiple targets: vigil of weak energy consumption, improvement of the false rejection rate alarms (in particular, those due to field noise battle and natural phenomena), device discretion, improvement of the probability of detection and improvement of the accuracy of the location of the intrusions, their tracking, the estimation of its velocity vector and the prediction of the future objective of the intruders

The teleoperation and telecontrol functions are secured by a two-way radio link between the bases floor and PC, allowing the following operations: control of operational availability of the ground bases, put into configuration and teleoperated management of the activity of these bases floor, and remote control of the good reception and the execution of radio orders concerning the commissioning configuration and management of the ground bases.

Because several bases of ground to cover a large area of land ensuring detection  and the location of objectives in automatic mode, it is necessary use an interconnection function between the ground bases.

In the presence of several targets (intruders), in order of synthesizing in the soil bases concerned, in the best way possible, the situation on the ground before transmitting it to the PC, several soil bases must be in a position to warn mutually of the arrival of information related to the detection of at least one intrusion. This is done by broadcasting a message. alert (to make the ground bases under vigil be awakened by those who have already detected a threat) and then by dissemination of the respective availability of the ground bases, in particular with a view to filling the gaps in the network.

The ground bases also ensure a evaluation function of damage caused to threats. To validate the effectiveness of the reaction, the acoustic sensors of the ground bases determine the impact points of the projectiles launched by teleoperated weapons in response to Intrusions confirmed. This allows to correct the parameters of shooting these weapons if no targets have been reached, how can prove it the evolution of the intruders trajectory after the reaction of teleoperated weapons, and proceed to a second Shooting. The coordinates of the impact points are transmitted to the PC so that your ballistic computer can automatically contribute the necessary corrections for the following shots.

As schematically represented in the figure 7, the command post (PC) is implanted in a light vehicle (shielded or not) 18. It essentially includes a computer attached to a information terminal 19, to a zone management terminal 20 and to emitters, for example in number of three, referenced with 21 to 23, and the operators necessary for the management and command of this Market Stall. The number of personnel necessary for the exploitation of the system is a function of the chosen mode of operation (automatic or of man in the treatment loop).

The information terminal 19 with its means of visual presentation allows you to collect the necessary information for the good management of the area to be protected 7 (movement of the friendly and enemy troops, weather messages, ...), communicate at the upper command level (5) the operational states of this zone 7 (intrusion detected, reaction performed, ...) and eventually involve the highest level of command in the decision of reaction.

The zone management terminal 20 with its calculation means allows, based on the knowledge of the contour of the zone 7 and the surrounding topography, to propose the means to be used by the protection device (number and position of teleoperated weapons and the ground bases, ...). It must allow a priori parameterization of the degree of involvement of man in the management of protection (automatic or manual management), as well as the level of intervention chosen (prohibition, deterrence, immobilization, destruction).
tion).

The PC has a cartography of the area a protect and from surrounding areas, allowing you to, directly from the information that comes through the network transmission, display the respective positions of the bases ground, deployed weapons, PC and information issued by the higher command network (weather messages, positions of friends and enemies, ...).

The PC computer includes a function of Intruder displacement management. Starting at information from the ground bases and those obtained by the higher level command network, the PC identifies the trajectories of intruders and can anticipate their evolutions to short term. In case of intrusion, the display screen of the terminal 20 and / or terminal 19 presents the base or bases of ground on alert, the main feature of the signature acoustics of the intruder or intruders, the location of the trajectory and speed of the intruder or intruders. This display is refreshed periodically (depending on the speed of change of this information).

The PC computer also includes a gun firing management function that optimizes the use of teleoperated weapons, for example to allow shot on moving targets. The device proposes a scenario of intervention defining: the weapon or weapons to be used, the point or the calculated impact points, ballistic parameters calculated (type of ammunition, aiming angles, adjustments of load, ...) and trip delays. In manual mode, certain parameters can be modified by the PC operator, and the Logistic calculations are adjusted accordingly. After the validation of these parameters by the operators, is launched automatically the teleoperation sequence of the weapons. In mode automatic, the reaction is activated without delay.

To ensure device teleoperation protection, the PC computer has a function of collective remote control of the ground bases and a function of Remote control of weapons. The remote control function of the bases of ground allows the operator to send: its setting in wake mode, his forced return as a wake after his awakening (for example, after the intrusion of a friend), its deactivation  and the control of its good state of operation. The function of remote control of weapons allows remote control directly via the PC computer for a complete shooting sequence according to the validated scenario, or the remote control of a weapon by the PC operator outside the intervention scenario.

The teleoperated functions for weapons are: the tensioning of the elements concerned, the adjustment of the ammunition, the load of the ammunition, the aim of the weapons, firing, return to waiting position of weapons and the control of the general good functioning of weapons. If Automatic teleoperation of weapons, several weapons can be mandated simultaneously to improve the overall effectiveness of the reaction.

The PC thus constituted allows to fulfill three different operational functions: zone defense in mode automatic, zone defense with intervention of the man in the loop and battery PC that is part of a gun section indirect (eg mortar) for infantry support. In effect, in the latter case, the ballistic module necessary for the use of teleoperated weapons can also be used to generate the shots of an indirect firing weapon section. In the case of a direct-fire weapon, the PC can be used to teleoperate the weapon, for actions in hostile zone.

Figure 8 shows the diagram of blocks of an example of teleoperated weapon for indirect shooting. This weapon, for example weapon 3.L, is mounted on a platform 24 easily scrollable, for example a platform that can be towed by a light or self-towed vehicle. 3.L weapon it comprises a weapon proper 25, for example a mortar or a grenade launcher, equipped with its aiming device 26 and its 27 position adjustment device, including these two devices means that allow to receive remote control orders. The 3.L weapon also includes an emitter-receiver of radio 28, a united teleoperation management computer 29, by one part, to the sender-receiver 28 and, on the other hand, to devices 26 and 27, a storage device 30 and ammunition adjustment and ammunition loading device 31. A source of electrical power 32 feeds all circuits electric and electronic weapon 3.L. To make a weapon teleoperated direct shooting, it will be necessary to add a camera observation (day / night) with a transmission of the signal to the PC.

As noted above, the weapon 25 may be, for example, a mortar. Advantageously, this can be a 120 mm mortar (type 2R2M), since it allows shooting on a hidden target at distances between 1 and 13 km, which allows it to adapt to the nature of the terrain (mountainous area, urban area, ...) and the extension of the area to be protected. Such mortar accepts a wide family of ammunition (cargo, explosives, illuminants, terminal guidance, ...) existing. The degree of reaction can thus be modulated depending on the events that occur in and around zone 7, which allows a good adaptation to the nature of the intrusion (troops, armored vehicles,
cars, ...). In addition, this mortar can be sent in teleoperated mode with a minimum of modification of its mechanical part. The teleoperated mode is made possible by an automatic aiming device subordinated to an angular setpoint value in elevation and azimuth (devices 26, 27) thanks to an automatic ammunition adjustment and loading device (30, 31) and thanks to a mortar management and control circuit (29) that is connected to the emitter-receiver 28 through an appropriate interface and thus allows the teleoperation of the weapon 25. Advantageously, the weapon thus automated can not only be integrated in a platform dedicated to the zone defense function, but it can also be integrated in a VCI type vehicle (...) to fulfill the support functions of the infantry.
tería.

The ammunition used is derived from the used for a towed mortar. Only loads propulsives are modified in order to allow automation of its adjustment Thus a modular modular propellant charge is obtained adaptable to each use case.

Platform 24 allows not only the displacement of the weapon, but also: great mobility and its ground anchor for shooting and equipment integration linked to the teleoperation of the weapon (elements 26 to 32). This platform is towable by a light vehicle and put in battery (deployment of the stabilization bars on the ground, radio antennas and put into wakefulness mode) is performed manually or automatically when in position. The capacity of storage device 30 is intended as sufficient to be able to carry a large number of different ammunition, which allows that the type of ammunition adapted to the reaction can be chosen, and This device can be easily replenished in the course of the reaction.

The effectiveness of the device of the invention is also secured by the transmission network to which they are united all its elements.

The links between the bases ensure the following exchanges between all these bases: dissemination of alert messages from a floor base that just detect an intrusion to all other soil bases and diffusion of a malfunction message from one broken down base to another base that has detected this fault to all other bases.

The links between the floor bases and the PC allow the PC to activate or deactivate all the bases or a part among them; and that they transfer from each floor base to the PC information concerning its operational status (good operation, fault, wakefulness, detection, ...) and information taken by their captors (arrival of an intruder, acoustic signature of this intruder, instantaneous position of the intruder, address and intruder travel speed, ...).

Advantageously, in order to get as far away as possible the PC (the only element of the device that needs personnel) of the area to be protected, radio repeaters are used between the PC and the set of bases, which greatly increases the distance between the PC and these bases.

In the device of the invention they ensure also links between the PC and teleoperated weapons in order to make these weapons sent by the PC (put under tension of electrical and electronic elements, aiming, charging the ammunition, firing, ...), and information is transferred from weapons towards the PC (aiming angles, nature and number of available ammunition, operating status of subsets, ...). Of course, the transmissions secured by the emitters-receivers 28 of the weapons and the Transmitters 21-23 of the PC are securized. The PC can send only several weapons for it teleoperated device or even its entirety.

The radio link between the PC (or PCs) and the upper level of command allows the PC to have information necessary for the management of the protected area (positions of friends and enemies, weather situation, ...) and have informed at the top level on the evolution of the situation in the area protected and around it (intrusions detected, reactions, ...)

The modularity of the device of the invention allows the ground bases to evolve independently and teleoperated weapons and, therefore, ensure a broad range of missions and new media are used as they go appearing, including these evolutions, for example, for:

-

        the ground bases: positioning devices (GPS type) that allow automatic dispersion (by rocket, from aircraft, ...), and improved detection means (sensor and algorithms of detection) that allow them to detect various natures of intrusions (infantrymen, aircraft, ...);

-

        Ammunition: new generations compatible with mortars, for example guided or corrected ammunition trajectory;

-

        Teleoperated weapons: mortars can be shipped in appropriate vehicles or mounted on an automotive platform teleoperated, allowing to deploy these weapons without exposing the personal. Other types of weapons can be used: other mortars type (for example, 81 mm mortar to treat intrusions of infantrymen), various artillery pieces to increase the extension of the area to be protected or the distance from servants of these pieces with respect to this area, weapons of proximity (smokers, ...) and non-lethal or energy weapons directed (powerful, acoustic electromagnetic pulse weapons, To be, ...).

A variant has been shown in figure 9 of deployment of the protection device of the invention. The zone 33 to protect is here, for example, a radar station of relatively small dimensions and the mission of the device protection is no longer destroying vehicles or infantrymen enemies that have been able to penetrate this area or make them retrace their way, but prevent them from approaching this area at a distance less than a safe distance (i.e. an equal distance within the supposed reach of enemy weapons that could destroy the facilities in zone 33).

The ground bases 2.1, ... 2.G are then arranged around zone 33 in all directions from where enemy forces are likely to reach. Weapons Teleoperated 3.1 to 3.F are also arranged around the zone 33 and directed towards the directions from where they may come the possible enemy forces. These weapons can be from any appropriate type: weapons of destruction, dissuasive, no lethal, ... In addition to the ground bases, the device of the invention may include advanced detection devices (by observation satellite, observation plane, ...). The PC and / or the higher level of command can also receive information from observers, in particular very observers next to the enemy lines, or even inside these lines.

The device of the invention has the following main advantages: it is modular and, therefore, offers great ease and rapid deployment, as well as good adaptability to each figure case, avoids the use of antipersonnel mines (the weapons that protect an area may be far from this area, which no longer needs to be mined), allows a graded response depending on the degree of intervention of the enemy forces (deterrence, partial or virtually complete destruction, ...) and an optimization of the means used (weapons and ammunition adaptable to the degree of reaction practically in real time, deployment of the ground bases and teleoperated weapons depending on the terrain configuration, the foreseeable enemy attack directions, the weather,. ..), easy evolution based on the availability of new
weapons, ...
