| 摘 要： | 本文采用蒙特卡洛(M-C)数值模拟,生成起伏高度满足高斯分布的随机粗糙表面。借助Kirchhoff近似,并在综合考虑辐射传输、光学及电磁学有关理论的基础上,利用M-C方法计算了符合高斯分布的一维随机粗糙表面的单次和多次光散射分布,模型结合射线追踪法考虑了粗糙表面的遮蔽效应。结果表明在考虑多次散射时,存在后向散射增强现象,该结论与实验结果相吻合,证明本文数值模拟方法的正确性。

| Abstract: | In this paper, one dimension Gauss random rough surfaces are created by the M-C simulation. On the basis of the Kirchhoff approximation combined with the radiative transfer, optics and electromagnetic scattering theories, the single and multiple scattering from random rough surfaces were investigated by means of M-C method. Enhanced backscattering was proved to be a result of multiple scattering. It indicates that the numerical results were available and reasonable. |
