Abstract

The invention provides a deceptive interference method and system for a gun sound positioning device and terminal equipment, which is suitable for use in the field of electronic countermeasure technology. The method includes: collecting an environment noise in real time, and converting the environment noise into an electrical signal; then extracting feature values of the electrical signal; and outputting a simulated gun sound when similarity of the feature values of the electrical signal and preset gun sound feature values reaches a preset threshold. A real gun sound is caused to be submergedin simulated gun sounds, then the gun sound positioning device is caused to fail to detect the gun sound or is caused to detect multiple false gun sound positions, thus difficulty of detection of thegun sound positioning device on sniper gun sounds is increased, and an effect of protecting a sniper at a side of us from being easily detected and identified is facilitated.

Description

technical field

[0001] The invention belongs to the technical field of electronic countermeasures, and in particular relates to a deception and interference method, system and terminal equipment for a gun sound location device. Background technique

[0002] Snipers are playing an increasingly important role in modern warfare because of their precision strikes and ability to defeat the enemy with one shot. The combat effectiveness of snipers that cannot be underestimated is mainly due to their excellent camouflage and concealment capabilities. In recent years, countries have continued to explore anti-sniper technology to detect enemy snipers earlier and faster on the battlefield.

[0003] The current anti-sniper technology mainly includes three methods of gunshot, infrared and laser detection. Among them, the gunshot location device uses the microphone array to detect the muzzle wave generated by the gunpowder explosion at the muzzle to locate the sniper. Passive and able to...
