| 摘 要： | 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。

| Abstract: | The statistical characteristics of rough surfaces are analysed and the relation between the spectral density of the rough surfaces and statistical parameters is found out.The backscattering coefficients of electromagnetic waves from rough surfaces are obtained with using Kirchhoff's diffraction theory and the statistical reflection coefficients.The supposition that signal characteristics of backscattering from ocean waves are of measurable is discussed in detail. |
