摘　　要：针对空间目标偏振探测识别的需求,研究了三类(保温膜、太阳能帆板、卫星涂层)六种(金色保温膜、银色保温膜、单晶硅、砷化镓、卫星涂层SR107和S781)典型空间目标材质偏振光谱反射特性。基于研制的材质偏振光谱测量装置测试结果进行分析,揭示了空间目标材质的偏振光谱特性空间分布规律。结果表明,光谱特性不随接收角变化,峰值特征波长不随检偏器角度变化;材质光谱半峰宽、特征波长以及保偏和消偏特性不随入射角变化,但不同入射角处光谱特征峰的峰值不同。文中研究对空间目标偏振探测具有重要的指导意义。According to the requirements of polarization detection and recognition for space targets, the polarization spectral reflection characteristics of six typical space target materials such as gold insulating film, silver insulating film, monocrystalline silicon, gallium arsenide, satellite coatings SR107 and S781 are investigated. The testing results of material polarization spectrum are analyzed, and the spatial distribution of polarization spectrum characteristics of space target is disclosed. The results show that the spectral characteristics don′t change with the detection angle, the spectral peak doesn′t change with the polarization analyzer angle. The half-peak width, characteristic wavelength, polarization retaining and depolarization properties of the materials don′t change with the incidence angle, but the values of characteristic spectral peak at different incidence angles are different. The work may provide guidance for polarization detection of space targets.
