Problems solved by technology
In order to process six-channel signals at the same time in this implementation, it is necessary to repeatedly use PIN diode switches and analog-to-digital conversion chips. The circuit area is large, and it is difficult to meet the requirements of the laser fuze.
[0007] Through the above analysis, it can be seen that the traditional signal processing method is difficult to meet the requirements of the laser fuze in terms of performance and circuit area.

Description
technical field [0001] The invention relates to the field of laser fuze signal processing, in particular to a laser fuze signal processing circuit and a signal processing method thereof. Background technique [0002] The laser fuze is a new type of fuze that uses laser beams to detect or perceive targets, and analyzes the echo signals reflected by the targets to determine the optimal detonation time of the warhead. In order to improve the operating distance and meet the requirements of omnidirectional detection, the laser fuze uses four or more detection channels, which requires its signal processing circuit to have multi-channel signal processing capabilities; in order to improve the anti-interference performance, the laser fuze adopts narrow pulse emission technology , it is required to accurately measure the delay of the reflected echo signal relative to the transmitted pulse signal (hereinafter referred to as the echo delay) and the pulse width of the reflected echo sign...
