Semi-active Laser Proximity Fuze

Abstract

The invention provides a semi-active laser proximity fuze, which relates to the technical field of laser detection and perception. The echo signal formed by the diffuse reflection of the laser is captured by the forward laser detection module and the circumferential laser detection module on the fuze. The wave signal is transmitted to the information processing module, and the information processing module comprehensively processes the target azimuth deviation angle in the forward laser detection module and the distance information in the circumferential laser detection module, and forms a detonation instruction according to the preset detonation logic. The best time to detonate the projectile. The intellectualization of conventional anti-aircraft artillery ammunition can be realized. After adopting the present invention, the conventional anti-aircraft artillery ammunition can be transformed and detonated without contacting the target. The target orientation and target distance can be sensed by the laser detection module. Thereby, the damage probability and damage effect of ammunition are greatly improved, the consumption of ammunition is reduced, and it is also possible to control the detonation timing of multiple projectiles at the same time.

Description

technical field [0001] The invention relates to the technical field of laser detection and perception, in particular to a semi-active laser proximity fuze. Background technique [0002] The laser fuzes used at this stage are mainly active type. The fuze emits repetitive pulsed laser light, and the beam is reflected after reaching the target. A reflected laser light is received by the fuze receiving system and converted into an electrical signal. After proper processing, the fuze is at a certain distance from the target. Detonate the warhead. [0003] Since the active laser fuze needs to be installed with a laser emitting and receiving device, and requires certain requirements for the sending and receiving device, there are problems such as large size and high cost, so it is difficult to install it on conventional ammunition such as small-caliber anti-aircraft guns. Conventional small-caliber anti-aircraft ammunition is generally equipped with a mechanical trigger fuze, and ...

Problems solved by technology

[0003] Since the active laser fuze needs to be installed with a laser emitting and receiving device, and requires certain requirements for the transceiver device, there are problems such as large size and high cost, so it is difficult to install it on conventional ammunition such as small-caliber antiaircraft guns

Conventional small-caliber anti-aircraft ammunition is generally equipped with a mechanical trigger fuze, and the fuze requires a direct hit of the projectile to destroy the target, so the probability of damage is very low
