一维随机粗糙面后向增强效应的蒙特-卡罗方法研究
A Study of Backscattering Enhancement of One Dimension Random Surface by Using Monte-Carlo Method
摘要
根据基尔霍夫近似方法, 用蒙特-卡罗方法模拟随机粗糙面, 观测到了随机粗糙面的后向增强效应。 分别研究了高斯粗糙面及分形粗糙面, 讨论了统计特性相同的粗糙面在不同小波尺度的电磁(光)波散射特性。 所得结果与实验事实相当吻合。
Abstract
Physics property of target and background is described by scarttering from rough surface. According to Kirchhoff approximation, backscattering enhancement of one dimension random surface is observed using Monte-Carlo simulations. Gauss rough surface and fraction rough surface are studied. Rough surface of the same statistical characteristic at different wavelet scale is discussed. The results are in accord well with experimental fact.
