本文就目前学者们所关注的电磁波与海浪随机粗糙表面的相互作用机理作某些探讨。主要分析了随机粗糙表面的统计特性,导出有关统计参量表式;运用了 Kirchhoff 衍射近似理论和统计反射系数获得了随机粗糙表面的电磁后向散射系数,并讨论了海浪后向散射信号特征量的可测定的设想。
This paper makes some discussions on the interaction mechanism between the electromagnetic wave and the random rough surface of ocean waves that scholars pay close attention to at present. The statistical properties of random rough surface are mainly analyzed, and the related statistic parameter tables are deduced. The electromagnetic backscattering coefficient of random rough surface is obtained by using the Kirchhoff diffraction approximation theory and statistical reflection coefficient. The characteristics of backscatter signals Measurable ideas.
