摘要
针对偏振成像激光雷达遥感的计算需求,在假设以散射体中心为主坐标系中心的情况下,研究了入射偏振光和散射偏振光坐标系的变换、散射体引起的偏振状态的变化以及散射矩阵与Mueller矩阵之间的几种最基本的变换关系,并从群论的观点给出了这些变换关系的描述。这些变换关系的进一步展开便可得到具体的激光雷达偏振遥感物理量的计算方法,这在解读偏振激光雷达遥感图像的应用中具有实际作用。
In order to meet the needs of computations for remote sensing of polarimetric imaging laser radar, the relation- ships about transformations between incident polarization laser coordinate system and scattering laser coordinate system, the changes of polarization state induced by scatter and the relationship between Mueller and scattering matrices are studied, which are based on the assumption that the centre of main coordinate system is the center of scatter. The studies are also based on the group theory approach. The calculation of polarization quantities can be obtained by expanding these transformations. The re- sults can play important role for interpretation of remote sensing image of polarimetric laser radar.
