Description

The invention relates to security and can be used, in particular, to counter radio-controlled explosive devices, information security, etc.

Known installation for disarming camouflaged radio-controlled explosive devices, the operation of which is based on the incapacitation of the sensitive elements of the receiver of the explosive electromagnetic radiation with adjustable parameters (US Pat. RU No. 54162 PM, publ. 10.06.2006. Bull. No. 16). According to a well-known solution, the source of electromagnetic radiation is a pulsed electromagnetic emitter mounted on a retractable support on a special vehicle and equipped with a pulse frequency regulator and a power regulator. The electromagnetic emitter extends to one - right - side of the vehicle so that the second - left - side remains unexamined, and possibly the explosive devices installed there are not neutralized. The disadvantages of the known solution include limiting the scope of application to the capabilities of a special vehicle, in particular, the impossibility of using explosive devices placed on rooftops, on rough terrain, etc. to neutralize explosive devices. In addition, another disadvantage of the device is a narrow and limited sector of surface inspection, namely, only on one side of the self-propelled chassis, which entails the danger of explosive devices being detonated from the opposite side of the installation in the direction of its movement. When an explosive device is destroyed, the source of pulsed electromagnetic radiation may be damaged or completely destroyed, and if the explosive device is high in power, the operators of this installation may also suffer.

The closest analogue of this invention is the PELENA-1000 automobile complex (http://kobra.su/catalog/avtomobilnyj/item/47-pelena-1000А/ date of access: July 23, 2021). The product is designed to protect the passengers of an escorted vehicle or a convoy of escorted vehicles from unauthorized eavesdropping using special radio devices and to prevent the operation of radio-controlled explosive devices (RCDs). The blocker is made in the form of a block of main transmitters and a power supply unit mounted in a metal rack. Depending on the type of car used, the blocks can be assembled in the form of a single rack, or they can be divided into several separate racks and blocks. Also, the product is equipped with four additional transmitters and fourteen remote antennas on magnetic bases for mounting on the car roof, a remote control with a 6-meter cable and a gas generator.

The disadvantages of the known solutions include the limitation of the scope of the capabilities of a special vehicle, in particular, the inability to use in difficult places. In addition, a lot of additional equipment is placed in the car (battery bank, gas generator, etc. - such equipment is difficult to carry by people, to be transported in small vehicles, etc.).

In general, the use of any blockers on the chassis, including for the purpose of blocking radio signals in a local area (including for the purpose of counteracting RVU or ensuring information security) will have significant "cons":

1) risk for service personnel (such a blocker must be delivered to a certain area);

2) it is not always possible to deliver a blocker due to transport accessibility;

3) the speed of delivery will also be quite long, which may adversely affect the safety of the population in the area of use.

In addition, it is clear that blocking from a high altitude (UAV) is more effective than from ground positions.

The technical objective of the invention is to create a method for blocking the signal in the local area of the location (movement) of a material object, including hard-to-reach places. In this case, a material object can be small in size (dimensions of a person, for example).

The solution of the set technical problem is achieved through the combined use of the following technical solutions:

- the use of an unmanned aerial vehicle for the delivery of a special installation that directly creates blocking of radio signals;

- due to the UAV performing the function of tracking, including a moving material object. Tracking is carried out by using an optical marker placed on a moving (or stationary) ground material object (for example, a car or a person).

To improve efficiency, the radiating antenna from the blocker (delivered by the UAV) can be brought closer to the ground object. This can be done by lowering the unmanned aerial vehicle above the object or by removing the radiating antenna together with the blocker from the body of the unmanned aerial vehicle on a special cable (or only the antenna can be removed from the body). In this case, the radiating antenna can be approached both separately and together with the blocker (depending on the tasks being solved, while significant losses must be taken into account when moving separately from the blocker RVU).

It should be clarified that in this application, as a blocker, we mean any device capable of interfering (usually by means of a generated signal) on certain radio frequencies (frequency bands). In various sources, such blockers are sometimes called jammers, communication blockers, jammers, noise generators, RVU blockers, etc.

As a blocker, for example, a blocker of the Grifon-10 type can be used (https://detsys.ru/catalog/antiterroristicheskoe-oborudovanie/blokatory-radiovzryvatelej/grifon_l0t/). The blocker of radio-controlled explosive devices GRTPHON-10T is designed to protect VTP persons from assassination attempt by blowing up a RVU located at any point on the route of a car. The GRIPHON-10T provides reliable blast protection for RDPs with receivers using virtually any modern communication standard. The blocker suppresses radio fuses in most communication frequency bands, including at the ultra-high frequency of 5 GHz.

Principle of operation and operation algorithm of GRIPHON-10T

The principle of operation of a car blocker of radio fuses is based on the generation of noise signals - barrage broadband interference. The interference generated by the GRIPHON-10T blocks the signals that are received by the RVU receiver. Protection against detonation is provided by suppressing signals designed to activate an explosive device.

The UAV performing the function of tracking a material object is illustrated in the figure (Fig. 1), where the positions indicate: UAV - 1 with a video camera 11, a ground material object 2, an optical marker 21.

The design of the ground material object 2 is not the subject of protection in this application. When accompanied by a UAV of a person, the marker can be applied, for example, to his helmet. When accompanying a car, the marker can be applied to the roof.

For marking, the use of a barcode (qr-code) is allowed. The fact is that many modern cameras are able to identify objects equipped with barcodes in automatic mode.

To increase the UAV control distance of a moving material object in a poorly lit area and / or at night, it is recommended to make an optical marker using luminescent paint.

At the same time, the height of the UAV can be set in advance when accompanying an object, and the height can also change according to a certain specified algorithm (for example, due to deterioration in visibility), or the operator himself can change the height in any possible way (including via radio channel).

At the same time, unlike other common methods of tracking UAVs of ground objects, this method does not require additional radio channels to communicate with the UAV (which is very important, given that the UAV has a load in the form of a communication blocker according to this method, which will block, among other things, channels UAV control)

The proposed method for blocking a signal in a local area where a material object is located works as follows.

A UAV with a special installation in the form of a blocker accompanies a material object from point "A" to point "B". At the same time, depending on the tasks, the frequencies (ranges) of blocker radiation can be selected (for example, tasks can be to block RVU, various leak channels, "bugs", etc.).

An identifying marking is applied on a ground material object by any known method, which will be an optical marker for the UAV.

It is preferable to apply an optical marker on the roof of a material object. This option is shown in Fig. one.

The UAV takes off and climbs, initially set in the device, which is part of the UAV design, or transmitted to this device in any known way.

A ground material object starts moving from point "A" to point "B". The video camera located on the UAV constantly monitors the optical marker. In FIG. 1 cone 13 symbolizes the field of view of the video camera. The calculation of the necessary corrections to the UAV heading occurs regardless of the absolute navigation coordinates of the ground material object, but only to eliminate the deviation of the boundaries of the video camera's field of view from the optical marker.

Due to the fact that a material object constantly accompanies a UAV with a special installation - a blocker in the local area of \u200b\u200blocation (movement) of a material object, the task of blocking communications at its (mat. object) location will be performed.

A ground material object can move over any rough terrain, and the only limitation is its passability. The possibility of the proposed method is limited to the movement of a ground material object in tunnels, but this case is quite rare.

Moreover, if a ground object makes a stop, the UAV “hovering” over it at a certain point in space.

The technical result of the application of the proposed method is a quick and safe blocking of communications in the local area of the location (movement) of a material object.
