摘要
应用Stokes矢量,Mueller矩阵以及双向反射分布函数4×4矩阵理论。计算了各种发射和接收偏振结构对目标散射信号的影响。建立了偏振可调的CO_2激光相干探测系统,并分别测量了光滑铝板和立方体角目标对各种接收和发射偏振结构的后向散射数据。发现偏振对目标测量(包括激光雷达目标定标)的影响是必须考虑的。
The influence of various polarization configuration transmitted and received on scattering signals of targets is calculated by employing Stokes vector,Mueller matrix and bidirectional reflective distribution function of'4 × 4 matrix theory. A polarization tunable CO_2 laser coherent detection system is established. The backscattering data of the target of Al-plate and cube corner to the various transmitted and received polarization configuration are measured. It is found that the influence of the polarization target measuring (including lidar target calibration) must be considered.
