Description

The invention relates to small arms systems, which can be equipped with optical and laser target indicators (sights) when used in combat conditions.

Currently, the armies of many countries of the world use small arms systems equipped with optical and laser target indicators (sights) to increase the effectiveness of their use in difficult conditions of warfare, especially when conducting anti-terrorist operations.

The disadvantages of this type of system is the high probability of accidental damage to their troops in extreme conditions of warfare, especially with poor visibility (night, smoke, fog, etc.), when visual recognition of the target is difficult.

Systems and devices that automatically recognize a target on the basis of the “friend or foe” principle and that prevent or substantially reduce the likelihood of defeating their military personnel during combat operations using small arms, including those equipped with optical or laser target indicators (sights), as a result of a patent search not found.

The aim of the invention is the creation of a device that automatically detects targets on the basis of "friend or foe" and prevents the accidental defeat of their troops during combat operations using small arms.

The purpose of the invention is achieved by the fact that in the weapon system of the military personnel, consisting of small arms equipped with a laser target designator (sight), and uniforms (body armor, jumpsuit, helmet, etc.) are additionally introduced: small arms - a system for coding radiation of a laser target indicator, its associated photodetector and decoding systems that control the device to ban shots from these weapons; in uniform - a transponder including a carrier base with optical fibers introduced into it, the input ends of which are distributed over the surface of the uniform, and the output ends are combined and, using an auxiliary lens and a color separator, are coupled to a photodetector that receives a coded signal at the wavelength of the laser pointer, and laser transponder emitting at a wavelength different from the wavelength of the laser target indicator and not perceived by the eye. Between the photodetector and the laser of the transponder, a decoder and encoder of the transponder are included.

The invention is illustrated in the drawing.

The drawing shows: small arms 1, military uniform 2, laser emitter of the target 3, encoder 4, color separator 5, output lens of the target 6, a photodetector with a narrow-band light filter 7, a decoder 8, a device for signaling and prohibition of shooting 9, the input ends of the optical fibers 10, the optical fiber 11, output ends of the optical fibers 12, auxiliary transponder lens 13, transponder color separator 14, transponder photodetector with narrow-band light filter 15, transponder decoder 16, transponder encoder 17, laser emitter of the responder 18, the signal device of the defendant 19.

A device for preventing the defeat of small arms of its troops on the battlefield works as follows:

When you aim at the target (your serviceman) located on a small arms 1, the laser emitter of the target 3 emits a signal encoded using encoder 4, which passes through the color separator 5, collimating the output lens of the target 6 and gets on the input ends 10 of the optical fibers 11 placed on the uniform of the military 2 . Through the combined output ends of the optical fibers 12, the auxiliary lens of the transponder 13 and the color separator of the transponder 14, the encoded signal is transmitted to the photodetector of the transponder 15 s narrowly a band-pass filter for the wavelength of the laser emitter of the target 3, and then to the input of the transponder decoder 16. After processing in the decoder of the transponder 16 and recognition of the encoder 4 code, the signal from the first output of the transponder 16 decoder is fed to the transponder 17 encoder, which generates the transponder's laser transducer 18 encoded response signal at a wavelength different from the wavelength of the laser emitter of the target indicator 3. Coded response signal through the color separator of the responder 14, an auxiliary object in the transponder 13 and the optical fiber 11 is radiated towards the laser target of the small arms 1 and, passing through the output of the target 6, the color separator 5 is fed to the input of the photodetector 7, which is equipped with a narrow-band filter for the wavelength of the laser emitter of the responder 18. From the output of the photodetector 7, the signal is received to the decoder 8, which, when recognizing the response code, generates a control signal to the signaling and barring device 9, providing a warning to the shooter about the target’s belonging and blocking shot.

The uniform of a soldier equipped with the proposed device allows, in addition, to provide a warning to a soldier about his exposure to laser target indicators (sights) with uncoded radiation or encoded using a cipher that does not coincide with the cipher of his side. For this, a second output is provided in the decoder of the responder 16, on which a signal is generated in case of a mismatch between the request cipher and its own cipher. This signal is fed to the signal device of the defendant 19 and warns the soldier about its exposure to extraneous (enemy) laser target designators (sights), which makes it possible to increase the survival of the soldier during the battle.
