偏振遥感是一种新型的侦察手段, 具有传统遥感所不具备的优点, 是研究大气与地面目标的重要方法.为了 研究伪装目标的偏振散射特征, 在光学与红外波段测量了三色迷彩伪装网的偏振参数.研究发现, 在探测条件一定 的情况下, 伪装网散射光的偏振度受入射角度和表面反射率的影响较大.入射角增大, 伪装网散射光的偏振度也随 之增大;表面反射提高, 其散射光的偏振度降低.偏振度成像可以增强低反射区域的亮度和对比度, 而偏振角成像 对伪装网的外形特征非常敏感, 偏振遥感对复杂背景中的低反射率伪装目标识别具有独特优势, 对**伪装目标 的生存构成了严重威胁

Polarization remote sensing is a new method with several advantages in detection. It is very important to study atmosphere and targets on the ground. To investigate the polarimetric scattering characteristics of camouflage targets, polarimetric parameters of three color pattern camouflage net were measured in visible and infrared waveband. By the analysis of data, it was found that polarimetric scattering characteristics of camouflage net were mainly influenced by incidence angle and reflectance of surface under a definite detecting condition. The polarization degree of scattering light goes up with the increase of incidence angle and falls when the reflectance of surface rises. The imaging of polarization degree can enhance the brightness and contrast of low reflectivity pattern, and the imaging of polarization angle is very sensitive to the outline of camouflage net. Polarization remote sensing is very useful to the detection of low reflectivity targets in complex backgrounds and threatens the existence of camouflaged military targets badly.
