Adaptive identification friend or foe system with early warning function based on low-light night vision sight

Abstract

The present invention proposes an adaptive friend-or-foe identification system with early warning function based on a low-light night vision sight. According to the characteristics of individual combat, an infrared signal in the near-infrared band 830nm-860nm, especially the 850nm band, is used to design an automatic Adapt to the identification friend or foe system, including a transmitter, a response terminal and an observation terminal. The transmitter has a housing, a laser transmitter, a control switch, a gear adjustment switch, and an optical axis adjustment knob. The response terminal has multiple signals set in different directions. Detection window, photosensitive detector, signal processing module and gear adjustment knob. Decode by the demodulation module to determine whether it is an optical signal emitted by a friendly party. If yes, respond and control the answering signal light to light up or flash in a predetermined way to identify it as a friendly party. If not, do not respond. Not only can friendly friend identification and enemy early warning be carried out quickly and reliably, but also it can effectively avoid the interference of ambient light on the identification of friend and foe, and reduce the possibility of misjudgment by the receiver of the identification of friend and foe.

Description

technical field [0001] The invention relates to the technical field of friend-or-foe identification in the field of individual combat, in particular to an adaptive friend-or-foe identification system with an early warning function based on a low-light night vision sight. Background technique [0002] With the continuous improvement of shooting accuracy, range and lethality of modern combat weapons, soldiers have to face the danger of attacks from enemy or other soldiers, air and ground vehicles and other weapon systems. In order to protect themselves or their comrades in arms, and at the same time, in order to effectively attack the enemy without accidentally injuring themselves, soldiers must know the attributes of the enemy and the enemy before the attack. Especially at night and in close combat, the enemy and the enemy may fight together intensively. It is impossible for soldiers to identify friend or foe through simple situational awareness, so the demand for an individu...

Problems solved by technology

[0004] The purpose of the present invention is to provide a self-adaptive identification friend or foe system with early warning function based on the low-light night vision sight, which solves the problem that the traditional simple strobe light is easy to be exposed, has strong concealment, and can carry out early warning at the same time
