摘　　要：空间目标光学散射特性建模与分析是空间光学监视系统论证设计、性能评价的前提和基础。以空间目标的可见光与激光散射特性为主要研究对象,分析了空间目标光学散射特性的基本研究内容和方法,介绍了国内外应用于卫星表面材料的比较典型的BRDF模型,从卫星表面材料BRDF测量与建模、目标可见光散射特性测量与仿真计算和空间目标LRCS测量与仿真计算三个方面,介绍了国内外典型研究单位的研究成果以及下一步的研究发展方向。可为空间目标光学特性研究思路与方法提供借鉴。Modeling and analysis of space target＇s optical scattering characteristics are the premise and foundation of the demonstration, design and performance evaluation of space optical surveillance system. The visible and laser scattering characteristics of space object were emphatically focuced in this paper, and the basic research contents and methods were discussed. The typical BRDF models of satellite＇s surface materials were introduced firstly, then the advances of foreign and domestic typical researches were introduced from three respects including surface materials＇ BRDF measurement and modeling, satellite＇s visible scattering characteristics measurement and calculating, and satellite＇s LRCS measurement and calculating. At last, the development orientation was put forward, which could provide references for the next research thinking and methods.
