摘　　要：针对激光引信在烟尘环境下探测时容易被烟尘散射和反射干扰引起虚警或漏警的问题,提出基于T矩阵法和Monte Carlo方法建立烟尘环境下脉冲激光的后向散射回波模型,进行905 nm脉冲激光在不同烟尘环境下无目标和有目标情况的仿真计算,研究不同烟尘浓度、不同收发间距和不同目标距离下的激光后向散射回波特性。通过现场试验,对比实测归一化值与仿真归一化强度值验证了脉冲激光在烟尘环境下的后向散射模型的精确度,为后续脉冲激光引信在烟尘条件下的抗干扰探测奠定了基础。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 establishment of a backscattering echo model for pulsed lasers in smoke and dust environments based on the T-matrix method and Monte Carlo method.Simulation calculations were conducted for 905nm pulsed lasers in the absence 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 backscattering model for pulsed lasers in smoke and dust environments was verified by comparing the measured normalized values with the simulated normalized intensity values.This laid a solid foundation for the subsequent anti-interference detection of pulsed laser fuzes under smoke and dust conditions.
