摘要
本文根据Ｋｉｒｃｈｈｏｆ近似下的多次散射理论和ＭｏｎｔｅＣａｒｌｏ数值模拟方法，分析了一维Ｇａｕｓ分布强粗糙表面（均方根斜率＞０．５）散射场的偏振特征。数值结果说明，单次散射仅在散射角很大时（θｓ＞６０°）产生非常有限的交叉退偏；后向附近的交叉退偏完全是在多次散射的过程中，场的两个正交分量发生不同位相变化而产生的。
This paper analyzes polarized multiple scattering from 1 D strongly rough Gaussian surfaces (rms slope>0.5) based on Kirchhoff approximation and Monte Carlo simulation.Numerical results shows that single scattering generates very limited cross depolarization only at large scattering angles ( θ s>60° ).Backward cross depolarization is completely due to different phase changes of two orthogonal field components durying multiple scattering progress.
