摘要
在介绍偏振成像机理的基础上,分析了偏振信息检测和强度信息检测在物理含义中的区别。以12种伪装网作为目标,通过实验研究了目标的反射光偏振特性,比较了它们的偏振光谱信息。分析结果表明:观测角度、目标表面粗糙度、目标材料等对目标偏振特性有很大影响。实验给出了观测角度、目标表面粗糙度、材料等与目标偏振特性的关系,对伪装目标检测具有重要的指导意义。
The differences of physics between the detection using polarization and using intensity are analyzed, which is based on the analysis of polarization imaging mechanism. The polarization characteristic of 12 kinds of camouflage net are com- pared. It is shown in the experiment that the observation angle, surface roughness and the materials of target are the main factors. Thus the results are effective to the problem of camouflage target detection.
