Individual friend or foe identification and laser warning device

Abstract

The invention discloses a friend-or-foe identification and laser warning device for an individual soldier, which is composed of an inquiry component installed on a weapon carried by an individual soldier and a response component equipped on the soldier. The interrogation component can transmit coded and modulated laser beams to unknown soldiers through coding and modulation circuits and infrared lasers; receive radio frequency response signals from friendly soldiers through the radio frequency receiving unit and give instructions through the indicating unit; at the same time, the infrared laser can also be used alone as a portable inquiry at night Component soldiers indicate target location. The response component identifies the laser radiation emitted by friendly or enemy troops through the laser detection unit, and responds to the friendly army’s inquiry signal through the radio frequency transmitting unit, and gives an audible and visual azimuth alarm to the enemy’s laser radiation. The main advantages of the invention are high sensitivity, good concealment, simple structure, small volume, light weight and low cost.

Description

technical field [0001] The invention belongs to the technical field of battlefield identification friend or foe, in particular to an individual soldier identification friend or foe and laser warning device including laser and radio frequency technology. [0002] technical background [0003] In modern warfare, the battlefield situation is becoming more and more complex and changing rapidly, and individual soldiers must make accurate judgments on the situation within a few seconds. Among all kinds of battlefield information, friend-or-foe identification and threat perception are the most important information sources. For the identification of aircraft and other large target equipment, many advanced identification systems have been developed for use on the battlefield. But the problem of individual soldier identification on the battlefield has remained largely unresolved until now, as warring parties no longer identify each other by individual soldiers' clothing and clear for...

AI Technical Summary

Problems solved by technology

[0005] The main disadvantages of the above system are: (1) The infrared light transmitter of the transponder can be seen by the enemy's low-light equipment, and it is easy to expose itself

(2) The system is too complex

(3) It only has the function of identifying friend and foe, and cannot warn the enemy's laser threat
