摘要
基于辐射度学原理给出激光引信回波仿真模型。目标表面材料的光散射特性用双向反射分布函数(BRDF)表征。目标和激光波束的相互作用由目标表面光散射特性、目标形状、激光脉冲的时间和空间分布决定。分析复杂目标近场回波特征与各影响因素的关系,结果可用于激光近炸引信目标探测算法设计,也可用于引信半实物仿真。
A model of laser fuze echo simulation based on radiometry is developed. Process of target/beam interaction is determined by target surface optical scattering proper ties, which can be characterized by bidirectional reflectivity distribution function （BRDF）. Signal features of the near-zone echo wave scattered from complex target are analyzed. The results may provide reference for algorithm design of laser proximity fuze. The simulator has been successfully applied in semi-physical simulation of the fuze.
