Abstract

The invention discloses a multi-channel laser fuse for all-direction detection. The laser fuse comprises a laser transmitter, a laser receiver and a signal processing unit, wherein the laser transmitter is used for transmitting detecting laser beams to a to-be-detected target; the laser receiver is used for receiving echo of the to-be-detected target and the echo of interference; the signal processing unit is respectively connected with the laser transmitter and the laser receiver, is used for generating a laser beam transmission standard time sequence so as to control the laser transmitter to transmit the detecting laser beams, and is also used for analyzing the echoes, received by the laser receiver, of the to-be-detected target and the interference so as to identify the to-be-detected target and realize environmental interference prevention and ultralow-altitude sea clutter interference prevention. The invention also discloses a method for detecting a target by adopting the laser fuse. The laser fuse and the method disclosed by the invention has the advantages of realizing large-view-field all-direction detection and being long in action distance, high in spot resistance and environmental interference resistance and applicable to the ultralow altitude field.

Description

technical field [0001] The invention relates to the technical field of laser fuzes, in particular to a multi-channel omnidirectional detection laser fuze and a method thereof. Background technique [0002] In recent years, new developments in technologies such as semiconductor lasers, diode-pumped solid-state microlasers (DPL) and microprocessors have provided a guarantee for the application of large detection field laser fuzes in the military field. In practical applications, it has evolved from providing a simple precision ranging function to control the explosion point to using laser beams to set different spatial layout methods, which can provide very accurate target distance and position information to achieve omnidirectional detection, Identify the target, and then achieve the purpose of precise distance and directional detonation. [0003] Laser emission field of view detection schemes are divided into multi-radiation schemes, partition schemes, partition scanning sc...
