Semi-active laser proximity fuse

Abstract

The invention provides a semi-active laser proximity fuse, and relates to the technical field of laser detection sensing. Through a forward laser detection module and circumferential laser detection modules on the fuse, echo signals formed through laser diffuse reflection are caught, and are then transmitted to an information processing module, the information processing module conducts integratedprocessing on the target azimuth deviation angle in the forward laser detection module and distance information in the circumferential laser detection modules, then a detonation instruction is formedaccording to preset detonation logic, and then ammunitions are detonated at the best opportunity. By means of the semi-active laser proximity fuse, intellectualization of common ammunitions for antiaircraft guns and the like can be achieved. After the semi-active laser proximity fuse is adopted, the common ammunitions for antiaircraft guns and the like can be modified, and detonation can be achieved even under the condition of not contacting any target. Through the laser detection module, the target azimuth and target distance are sensed, thus the damage probability and damage effect of the ammunitions are greatly improved, the consumption quantity of the ammunitions is reduced, and control over the time to detonate multiple ammunitions simultaneously can also be achieved.

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
