摘　　要：介绍了双向反射分布函数测量空间目标表面材料热特参数的原理和方法,搭建了双向反射分布函数光谱特性和激光散射特性测量平台,对空间目标的几种典型热控涂层反射率进行了测量。测量结果表明,在入射角为0°时,SR107白漆涂层的反射率为0.785;OSR,F46和聚酰亚胺薄膜对532 nm激光的反射率均大于90%。To achieve the simulation for 1R detection of spatial targets, analysis and analogy calculation of the temperature field of the target in spa is needed. One of the most important boundary condition is the surface material natural parameters of targets. Bidirectional reflectance distribution function（BRDF） method to measure target surface reflectance is studied and the BRDF measuring spectrum and laser reflectance feature platform is built. Thermal parameters of some typical thermal control coating on spatial targets are measured. The measuring tests indicate that the reflectance of white paint coating SR107 is 0. 785 while the input angle is 0°. The tests also show that the reflectances of OSR,F46 and polyimide-thin-film are greater than 90%.
