摘　　要：针对粗糙表面散射的后向散射增强现象,采用锥形波束入射的矩量法定量计算了高斯、分形和限带粗糙海面模型的后向散射增强效应,研究了高斯和分形模型的波形参数和表面尺寸的匹配问题,分析了三种模型在不同入射角下散射增强的角宽度,比较了不同风速、不同粗糙度和不同分维数下散射增强的峰值和角宽度。Focusing on the backscattering enhancement effect of Gaussian, fractal and bandlimited ocean spectrum rough sea surface, the moment of method associated with the tapering incident wave is adopted. The matching problem for the tapering parameter and the rough surface size under different incident angles with Gaussian and fractal model is studied. The angular width of backscattering enhancement for the three models is compared. The angular width and the amplitudes of enhancement under diverse wind speed, roughness and fractal dimensional numbers are analvzed with this method.
