UA118353U - SYSTEM OF DETECTION, RESPONSE AND DESTRUCTION OF SMALL DIMENSIONAL UAVES - Google Patents

Abstract

The system for detecting, counteracting and destroying small-scale unmanned aerial vehicles consists of means of detection and aiming and means of counteraction and damage. Optical-electronic device for search and tracking of targets in the visible and thermal ranges, acoustic detection equipment and radio direction finding equipment were installed as means of detection, and radio-electronic counter-attack equipment and at least one automatic ammunition-fired automatic cannon were installed as counteracting means.

Description

The useful model belongs to the field of air defense, in particular to the means of destroying highly maneuverable aircraft with a low reflective surface area with low altitude and flight speed, namely to the systems of destruction of small-sized unmanned aerial vehicles in flight, and can be used to destroy low-speed enemy air targets, that fly low, such as an airplane, helicopter or remotely controlled unmanned aerial vehicle, as well as lightly armored ground targets.

There are known systems (1) in which the specified small-sized unmanned aerial vehicle is affected by means of destruction, which include small arms bullets, cannon shells of various calibers and rockets - guided and unguided, but such systems require the use of a large number of bullets (if fire is fired from an 5.45, 7.62, 12.7 or 14.5 mm caliber weapons) or projectiles (if fired from 23 or 30 mm small-caliber guns) with a high density of fire, and the probability of hitting the unmanned aerial vehicle remains probable. The destruction of small unmanned aerial vehicles by missiles, especially guided ones, is economically impractical and requires accurate determination of the location of the target, in addition, the missiles need time to prepare for launch and capture the target.

A well-known system (21), which destroys the enemy’s small-sized unmanned aerial vehicle in flight by detonating ammunition in close proximity to the target, and the ammunition carrier in this case is an unmanned aerial vehicle equipped, in addition to regular systems and equipment, with a video surveillance system with a video camera, fragmentation ammunition or high-explosive action and the activation system of these munitions, but this system requires the accurate bringing of the munitions carrier in close proximity to the target and the subsequent timely detonation of the munition, in addition, spending one unmanned aerial vehicle to destroy another is economically impractical.

The closest technical solution, both in essence and in terms of the problem to be solved, which was chosen as the closest analogue (prototype), is a system of detection and defeat of UAVs, made on gyro-stabilized platforms, on one of which a circular view camera, an acoustic sensor and a sensor that works in three or more radar ranges, and a launcher for anti-aircraft missiles is mounted on the other |Z), but this system requires the use

From several detection platforms to correctly determine the coordinates of the target, and the use of anti-aircraft missiles to destroy unmanned aerial vehicles is economically impractical. In addition, the communication between the platforms is carried out using a laser channel, but as you know, the laser requires a direct line of sight between the transmitter and the receiver, and also suffers significant interference and loss of range in bad weather conditions. The declared possibility of using a system with gyro-stabilized platforms on a moving object requires the use of an expensive chassis with a large load capacity.

The useful model is based on the task of increasing the effectiveness of defeating unmanned aerial vehicles while simultaneously reducing the cost of destroying unmanned aerial vehicles and without increasing the level of visibility of the system.

The essence of the useful model is explained by the diagram shown in the drawing, which shows the block diagram of the system for detecting and destroying small unmanned aerial vehicles in flight.

The claimed system of detection, countermeasures and destruction of small unmanned aerial vehicles performs target detection using radio direction finding equipment 1 and optical-electronic device 2 and their further destruction by means of radio-countermeasures 8 and the fire of a rapid-fire automatic gun 5. Automatic gun 5 and an optical-electronic device 2 are mounted in an uninhabited high-speed combat module 6. To destroy small-sized unmanned aerial vehicles in flight, the gun 5 is equipped with air blast ammunition 7. The optical-electronic device is equipped with means of observation in the visible Z and thermal 4 ranges. In addition, the indicated system can be mounted on an armored all-terrain chassis 9, as well as equipped with an additional means of detection - acoustic detection and observation equipment 10.

Thus, in the declared system, an increase in the effectiveness of detecting, countering and defeating small-sized unmanned aerial vehicles in flight is ensured in comparison with the prototype due to the fact that the means of detection include an optical-electronic device, which contains a thermal imaging channel in addition to the television channel available in the prototype , as well as acoustic and radio direction-finding devices, unlike the prototype, which uses a radar.

The proposed system includes radio countermeasures equipment capable of disabling small-sized unmanned aerial vehicles without the use of firearms. Fire 60 means of destruction are equipped with air blast ammunition, one of which in terms of its impact properties corresponds to several dozen ordinary bullets or shells, and the cost of one air blast projectile is much less than the cost of, for example, an anti-aircraft missile or several dozen ordinary bullets or shells.
