Individual soldier oriented identification-of-friend-or-foe device and identification-of-friend-or-foe helmet based on MEMS infrared light source

Abstract

The invention proposes an individual soldier oriented identification-of-friend-or-foe device based on MEMS infrared light source, and the device comprises an infrared light source component. The infrared light source component comprises a radiation distributor. The radiation distributor is arranged in a centrally hollow round table structure and the inclined angle of its bus is 60 degrees. The arc side wall of the radiation distributor is provided with a plurality of radiation faces that are distributed in an annular shape. The top wall of the radiation distributor is also provided with a radiation face. Each of the radiation face is provided with a plurality of MEMS infrared light source components. The inner part of the radiation distributor is provided with a control panel used to control the MEMS infrared light source components. The identification-of-friend-or-foe helmet comprises a helmet. The helmet is provided with the identification-of-friend-or-foe device. The individual soldier oriented identification-of-friend-or-foe device and the identification-of-friend-or-foe helmet proposed by the invention cooperate with the airborne photoelectric equipment of an existing airplane and determine the position and other information of a target through the recognition of the infrared photoelectric signal of the target. Absent from the electromagnetic interference and influence, the device and the helmet can be used in hostile weather and has a strong ability to recognize a target.

Description

technical field [0001] The invention relates to the field of identifying friend or foe devices, in particular to an identifying friend or foe device for individual soldiers and an identifying friend or foe helmet based on MEMS infrared light sources. Background technique [0002] On the modern battlefield, due to the fuzzy boundary between the enemy and the staggered activities of both sides, it is very important to perform real-time, accurate and rapid identification friend or foe (IFF) to avoid accidental injury. Individual equipment is a device that is easy to use, easy to carry, and can send out infrared photoelectric signals. When used with an airborne infrared thermal imager, the pilot can quickly identify the attributes of individual targets and grasp the initiative on the battlefield. [0003] The traditional identification friend or foe equipment is an inquiry-response type, based on radar or laser communication, which is not only susceptible to electromagnetic inte...

AI Technical Summary

Problems solved by technology

Traditional infrared light sources are mainly infrared light-emitting diodes and infrared blackbody thermal radiation light sources, which are large in size, poor in modulability, and have serious red storm effects. MEMS infrared light sources have the advantages of high radiation intensity, modulation, and coverage of medium and long-wave infrared bands. They are suitable for Infrared target identification in various fields

The MEMS infrared identification technology that has been researched in China is mostly used in the infrared communication system of large targets and stations, and has not yet been applied in personnel search and rescue and identification of friend and foe
