摘　　要：本文分析表面不规则物体电磁波的散射特性．采用程函近似计算了其散射强度角分布．结果显示，表面不平度和散射强度局部最大值及后向散射增强效应密切相关．In this paper,we analyse the scattering of an electromagnetic wave with a centimetric wavelength by an object whose surface is irregular. The angular dependance of the intensityscattered is obtained in the framework of the eikonal picture. Using different types of surface ourresults show a correlation between the irregularities and the local maxima in the intensity spectrumand a systematic backscattering enhancement.
