Description

Technical field

The method of remote demining relates to the field of military engineering, demining and counter-terrorism means, and is intended to ensure the safety of movement of units of special military equipment, weapons and vehicles along the routes.

The remote demining method is used to eliminate explosions at a safe distance, as well as to remotely block engineered ammunition and improvised radio-controlled explosive devices (IEDs) containing electronic components.

Level of technology (analogues)

A method and device are known according to the description of patent No. 2497155 (RU) Method and device for detecting anti-personnel explosive devices (ED) with contact-wire target sensors [1].

According to the description of patent No. 2497155, the method for detecting anti-personnel explosive devices with contact-wire target sensors is that the conductor is excited by a frequency-tunable electromagnetic field with a frequency range overlap coefficient of at least two and a recorded rate of change in the amplitude of the reflected signal.

The disadvantage of this method is that the implementation of the method requires a small and dangerous distance to detect a mine and selective detection of a device only with contact-conductor sensors.

A method for demining is also known according to the description of the invention for patent No. 2310811 “Method for neutralizing camouflaged radio-controlled explosive devices” [2]. According to patent No. 2310811, the technical result is achieved by creating moving pulsed electromagnetic radiation in the area where radio-controlled explosive devices are predicted to be planted: along roads, highways, streets and piers, in squares and stadiums. If there are radio-controlled explosive devices (REDs) in such areas, the radio receiver is rendered unusable or destroyed.

The disadvantage of this method is the process of neutralizing the explosive device, which is localized only in the area of the predicted planting on the sides of roads and highways, at a very close and unsafe distance from the source of pulsed electromagnetic radiation, therefore, when destroying the explosive device, the source of pulsed electromagnetic radiation itself may be damaged or completely destroyed. From the description of this method, a technical drawback also follows, consisting in the fact that the source of pulsed electromagnetic radiation generates signals with pulsed frequency parameters that require coordination with the speed of movement of electromagnetic pulsed radiation (EPR). In addition, the need to coordinate the speed of movement and the parameters of EII indicates the low energy and electromagnetic characteristics of the radiation, as a result of which the technical reliability of mine clearance is reduced.

Despite these disadvantages, the specified technical solution of the method according to the description of the invention to patent No. 2310811 [2] can be accepted as a prototype, as the closest analogue.

The technical task and technical result of the invention is to create a reliable and safe method that provides remote neutralization and destruction of radio-controlled and other explosive devices at a remote safe distance.

The essence of the proposed method for remote mine clearance is the generation of pulsed electromagnetic signals.

The signals are transmitted to pulsed electromagnetic field emitters.

Radiation of a pulsed electromagnetic field is performed.

They influence explosive devices and explosive devices with electronic components (VUEK) with a pulsed electromagnetic field (EMF).

They block explosive devices with electronic components.

The liquidation of VUEK is carried out by detonation.

In this case, a pulsed microwave signal is generated.

In this case, an ultra-wideband high-frequency (UWB-HF) signal is generated.

At the same time, microwave and UWB-HF signals are transmitted to spatially oriented emitters of the microwave and UWB-HF electromagnetic field.

In this case, spatially oriented microwave and UWB-HF signals of the electromagnetic field are simultaneously emitted in a given direction of remote mine clearance.

In this case, the emitters of directional microwave and UWB-HF EMF signals are continuously moved simultaneously.

At the same time, directed microwave and simultaneously directed UWB-HF EMF radiation is moved along a given demining route.

Description of special cases

During the mine clearance process, UWB-HF EMF radiation is directed, possibly oriented in a vertical plane.

During the mine clearance process, UWB-HF EMF radiation is directed, possibly oriented in a horizontal plane.

During the demining process, directed UWB-HF EMF radiation is oriented in the vertical plane and preferably simultaneously carries out radiation oriented in the horizontal plane.

During the demining process, directed microwave electromagnetic field radiation is preferably performed simultaneously with scanning of the spatially oriented axis of directed microwave radiation in the target horizontal sector.

Implementation of the method

At the first stage, an electromagnetic signal of ultra-high frequency (microwave) and ultra-wideband high-frequency (UWB-HF) signal of specified modes and parameters are generated.

The energy and electrical modes of the generated pulsed electromagnetic signals are selected within specified limits.

For example, to generate a microwave signal, the characteristics are preferably selected within the range:

- pulse power of at least 1.5 MW;

- radiation wavelength 23.5…23.7 cm; (1.271 GHz);

- pulse duration 3.5...4.5 μs;

- duty cycle of pulses from 900 to 1000.

For example, to generate a UWB-HF signal based on a generator (GIN 3-500), the radiation parameters are selected, possibly within the limits:

- max. amplitude of voltage pulses (50 Ohm load) - 3.0 kV;

- pulse rise time - 200-300 ps;

- max. pulse repetition frequency - 1 MHz;

- duration of electromagnetic pulses at the level of 0.5 amplitude - 0.2...0.3 ns.

At the second stage, pulsed electromagnetic signals are transmitted, for example, through feeder paths, to spatially oriented microwave and UWB-HF electromagnetic field (EMF) emitters.

At the third stage, spatially oriented microwave and UWB-HF signals of the electromagnetic field are emitted in the direction of remote mine clearance.

For example, the EMF radiation flux density is chosen within the range of at least 0.3 W/cm ² at a distance of up to 100 meters from the SSH HF emitters, as well as the EMF intensity (at least) 30 V/m at a distance of up to 100 meters from the microwave EMF emitters.

At the fourth stage, remote exposure of explosive devices with electronic components (VUEK) is carried out by radiation of microwave and UWB-HF signals of the electromagnetic field, the VUEK is removed from the explosive state by blocking and/or by remote actuation of the VUEK fuse (triggering and liquidation by remote detonation ) at a safe distance.

At all of the above stages, the process of moving directional emitters of microwave and UWB-HF radiation signals and, at the same time, the process of moving directional polarized UWB-HF and scanning microwave EMF radiation along a given sector and demining route are performed.

At all of the above stages of the proposed method of remote demining, the safety and integrity of the directional emitters of microwave and UWB-HF signals is ensured due to the remote detonation of the VU and/or VUEK at a remote safe distance, as well as due to the protected location of the emitters of the microwave and UWB-HF signals.

Thus, the effect of remote demining, detonation of explosive devices, blocking of VUEK is obtained due to the joint directed radiation of ultra-wideband high-frequency (UWB-HF) and ultra-high-frequency (microwave) electromagnetic fields that create radio interference, and also simultaneously create induced currents in the conductive elements and electrical circuits of the radio receiver of the fuse , disabling these elements and the entire radio receiver as a whole, as well as receiving induced currents on the electric detonator, with the aim of its failure, operation, detonation and remote destruction (liquidation by detonation) of VUEK and other explosive devices (explosive devices) at a remote safe distance.

Examples of concrete implementation

In order to block VUEK and remote mine clearance, UWB-HF EMF radiation is carried out with polarization in the vertical plane, while simultaneously moving along the mine clearance route.

In order to block VUEK and remote mine clearance, UWB-HF EMF radiation is carried out with polarization in the horizontal plane, while simultaneously moving along the mine clearance route.

In order to block VUEK and remote mine clearance, UWB-HF EMF radiation is carried out with polarization in the vertical plane and, at the same time, radiation with polarization in the horizontal plane, with simultaneous movement along the mine clearance route.

For the purpose of remote demining, the area along the demining route is irradiated with a microwave electromagnetic field simultaneously with scanning the spatially oriented axis of directed microwave radiation in a limited target horizontal sector, with simultaneous movement along the demining route.

The practical use of the remote mine clearance method lies in its use for the operation of executive electronic microwave devices for remote mine clearance based on mobile and other vehicles.

The implementation of the proposed technical solution is not limited to the above examples.

The technical result of the method is achieved due to the fact that they create radiation of a microwave and UWB-HF pulsed electromagnetic field with the proposed energy and electromagnetic parameters in horizontal and vertical polarized planes when moving along a mine clearance route with simultaneous horizontal scanning of microwave EMF in a directed target sector.

The authors of the invention tested the claimed method, which confirmed the achievement of the technical result.

The method was tested while moving microwave and UWB-HF emitters of ultra-high frequency EMF at a speed of about 15 km/h using special vehicles. The values of the technical characteristics of the method implementation are given in the table:

The effectiveness of the remote demining method for detonating and blocking explosive objects has been confirmed by experimental field tests on samples of engineering ammunition in a total of 20 units (special assemblies of fuses of various types). As a result of the tests, it was discovered that 18 units of special fuze assembly samples were triggered and 2 units of special assemblies were blocked, that is, in total, all 20 units or 100% of the samples worked. Remote operation (clearance) of special assemblies occurred at a distance of up to 100 meters from the applied actuators of the method (from microwave emitters and UWB-HF emitters of ultra-high-frequency EMF).

A comparative analysis showed that the obtained and practically tested modes and selected parameters of the developed method of remote demining fully ensure the performance of the demining function within the specified limits and characteristics.

Thus, the technical task of creating a reliable and safe method that provides remote neutralization and destruction of radio-controlled and other explosive devices at a remote safe distance is ensured.

The inventive method of remote demining is implemented using industrially produced devices and materials, can be implemented at any enterprise in the radio-electronic industry and will find wide application in military equipment and in the fight against terrorism.
