摘要:

利用多波段偏振CCD相机在光学与红外波段测试伪装涂层的偏振散射特征,并提取其中的偏振信息,研究了测试条件对涂层材料散射偏振度的影响.结果表明,测试过程中的光照条件与探测波段对涂层散射偏振度的影响很大.涂层对入射光的散射作用可以分为面散射和体散射两部分.面散射使偏振度增大而体散射具有消偏振的作用;光线垂直入射时,体散射起主要作用,涂层具有较小的偏振度;随着入射角的增大,面散射在散射光中的比例也逐渐增大,成为涂层偏振度的主要影响因素.研究发现在偏振遥感中利用合适的角度和波段进行探测对复杂背景中伪装目标的识别具有重要意义.

Abstract:

The polarization scattering characteristics of camouflaged coatings were tested by multi-band polarization CCD camera in the optical and infrared bands, and the polarization information was extracted, and the influence of the test conditions on the scattering polarization degree of the coating materials was studied. The results show that the illumination conditions and detection band during the test have a great influence on the scattering polarization degree of the coating. The scattering effect of the coating on the incident light can be divided into two parts: surface scattering and bulk scattering. Area scattering increases the polarization degree and bulk scattering has the effect of depolarization. When the light is incident perpendicularly, bulk scattering plays a major role, and the coating has a small degree of polarization; With the increase of the incidence angle, the proportion of surface scattering in the scattered light gradually increases, which becomes the main influencing factor of the polarization degree of the coating. It is found that the use of appropriate angles and bands for detection in polarization remote sensing is of great significance for the recognition of camouflaged targets in complex backgrounds.
