| 摘 要： | 基于随机面元模型，建立了海面对激光散射的理论模型，详细分析了海面散射的退偏振特性。理论分析表明：除后向外其它方向的散射光都存在部分退偏振现象；但是浮于海面上或悬浮于海面的物体表面对激光散射所具有的退偏振特性明显不同于海面散射的退偏振特性。因此可以根据这些差异来遥感海面的漂浮或悬浮物体，该结论已经被实验证实。

| Abstract: | This paper presents the theoretical evaluation for the laser scattering from the waved seawater surface with the random facet model and the depolarization property of the seawater surface. The numerical results show that the scattering light is partly depolarized in all direction except the backward. If the local incident angle equals to the Brewster angle, the scattering light will be linearly polarized for any incident laser. A simulating experiment was done to verify the theoretical analysis, and the result agrees well with the calculating one. |
