通过引入偏振函数扩展物理模型，建立矢量化物理模型（VPM），分析了星载激光雷达观测到的水云多次散射退偏振比的垂直分布。由于单次散射，在束多次散射，和脉冲展宽机制的退偏比分别处理的VPM。VPM还包括一个高阶散射矩阵，并适应在多次散射过程中修改偏振态的机制。从VPM的退偏振比的估计的配置文件显示出良好的协议与蒙特卡罗模拟，平均相对误差约为2% +/-3%。(C)根据OSA开放获取出版协议的条款，2019年美国光学学会
A physical model was extended with a polarization function to create a vectorized physical model (VPM) to analyze the vertical profile of the observed depolarization ratio due to multiple scattering from water clouds by space-borne lidar. The depolarization ratios due to single scattering, on-beam multiple scattering, and pulse stretching mechanisms are treated separately in the VPM. The VPM also includes a high-order scattering matrix and accommodates mechanisms that modify the polarization state during multiple scattering processes. The estimated profile of the depolarization ratio from the VPM showed good agreement with Monte Carlo simulations, with a mean relative error of about 2% +/- 3%.
