：对几种典型目标的后向散射光偏振度进行了测量和分析。基于探测光的Stokes矢量描述，利用接收光路和发射光路的一体化设计，设计了典型目标偏振特性的激光探测实验装置；在不同偏振光入射角、不同粗糙度参数以及不同表面材质的条件下，对几种典型目标后向散射光的偏振度进行了测量；在实验的基础上对偏振度测量数据进行了双高斯拟合和分析，得出了目标后向散射光偏振度与双高斯函数基本吻合以及基于后向散射光偏振度可以区分不同属性目标的结论。

The degree of polarization of backscattering laser, which is scattered from several typical targets, was measured and analyzed. Basing on the description of detection laser with Stokes vector, experimental setup of laser detection for polarization characteristics of typical targets was designed using the transceiver integration; the degree of polarization of backscattering laser of several typical targets was measured under the conditions of different angle of incidence laser, different roughness parameters and different materials of target surface; the measurement data of degree of polarization was analyzed after double Gaussian fitting on the basis of foregoing experiments, two conclusions that the degree of polarization of backscattering laser highly fits the double Gaussian function and targets with different attributes can be distinguished using the degree of polarization of backscattering laser were achieved at last.
