摘要 偏振特性是光与物质相互作用所表现的重要特性之一,与物质的性质密切相关。空间目标偏振特性可能会因为特定空间目标组成材料和空间目标轨道不同而存在差异,因此为空间目标的探测和识别提供了科学依据。本文通过空间目标材料以及典型空间目标模型的多角度偏振成像特性试验测量,分析了空间目标偏振特性及其变化机理。结果表明,空间目标表面材料的偏振特性对于目标的识别具有很重要的作用,太阳能电池板的姿态对卫星的偏振特性影响尤为明显。本文研究可以为空间目标光学偏振探测与识别提供应用基础研究支持。 Polarization is one of the important optical characteristics of target.Certain materials used in constructing satellites possess unique polarization because of certain space target designs and different orbits.Thus polarization can be considered for target detection and recognition.Photopolarimetric characteristic of space target materials and model are measured and analyzed.Results show that the polarization properties of material are significant for target detection,and the attitude of solar panel has great effect on the polarization of satellite.This research can give support to the application for space target detection and recognition.
