偏振遥感在伪装目标识别上的应用及对抗措施

 为了研究偏振遥感对伪装目标的识别特点，分别对不同颜色的伪装网进行了偏振参数测量和成像实验。通过数据分析发现，伪装网的散射偏振度受观测条件和材料自身特性（如反射率、折射率和表面粗糙度）影响很大；伪装涂层对入射光的散射作用可以分为面散射和体散射，其中面散射具有起偏振作用而体散射具有消偏振作用；与自然背景相比，伪装目标的偏振特征非常显著，利用偏振遥感可以有效地识别出常规侦察手段所不能发现的伪装目标。通过偏振遥感的侦察原理和特点分析，提出了可以利用表面结构设计和烟雾等方法对抗偏振遥感的侦察。

Application of polarization remote sensing in camouflage detection and method of polarization stealth

Polarimetric parameters and polarization imaging of camouflage net were measured to study the effect of polarization remote sensing on the camoulflage targets.It is found that the polarization degree of camouflage net was greatly influenced by the condition of detection and characteristics of materials, such as reflectance, refractive index and roughness of surface. The interaction between incident light and camouflage coating can be divided into two parts, surface scattering and volume scattering. Surface scattering act as a function of polarization and volume scattering act as a function of depolarization.The polarimetric characteristics of camouflage targets were different from natural background. Compared with traditional remote sensing, polarization remote sensing can find the camoufl
