Backscattering Echo Characteristics of Pulse Laser Fuze in Dust Environment
Laser fuzes are prone to false alarms or missed detections due to the interference caused by scattering and reflection of smoke and dust during detection in smoke and dust environments,this paper proposed the es-tablishment of a backscattering echo model for pulsed lasers in smoke and dust environments based on the T-ma-trix method and Monte Carlo method.Simulation calculations were conducted for 905nm pulsed lasers in the ab-sence and presence of targets under different smoke and dust conditions,studying the characteristics of laser backscattering echoes under various smoke and dust concentrations,different distances between the transmitter and receiver,and different target distances.Finally,field tests were carried out,and the accuracy of the back-scattering model for pulsed lasers in smoke and dust environments was verified by comparing the measured nor-malized values with the simulated normalized intensity values.This laid a solid foundation for the subsequent an-ti-interference detection of pulsed laser fuzes under smoke and dust conditions.
