Abstract
To improve the detection performance of the pulse laser fuze circumferential detection system, this paper studies the echo
characteristics of pulse laser fuze circumferential detection system and the adaptive filtering method of the echo signal under
the cloud and fog environment. Based on the working principle of laser fuze and the constraint conditions that the system can
detect ground targets, the calculation functions for the minimum scanning frequency of laser circumferential detection and
the minimum pulse frequency of pulse laser are established; Due to the influence of cloud and fog environment on the echo
signal, an adaptive filtering method is used to filter out interference signals and restore the real echo signal detected by the
system. By integrating the detection model of the system for ground target, the echo power calculation mathematical model
is derived using the bidirectional reflection distribution function. The filtering effect of adaptive filtering method on echo
signals under different external interference factors, as well as the detection probability of the system under different motor
scanning frequencies and laser pulse frequencies, were simulated and analyzed. The results demonstrate the feasibility of
proposing the mathematical model and signal processing method in this paper.
