摘　　要：针对矩量法(MOM)不能有效求解大尺度粗糙介质表面散射特性的问题,采用基于物理的双网格法(PBTG)快速计算了高斯粗糙海面的散射特性,对比了不同矩阵维数下的求解时间,研究了水平、垂直极化下粗糙海面的散射增强现象。通过与矩量法的比较,证明了PBTG法的高效性。The classic method of moment （MOM） can not calculate the scattering characteristic of large - scale rough surface, in view of this problem, the scattering effect of Gauss rough sea surface is calculated quickly with the physics - based two - grid （PBTC） method. The calculation time for different matrix dimensions is compared. And the scattering enhancement effects of rough sea surface are studied at plane - polarization and perpendicularity - polarization with this method. The comparison between MOM and PBTC methods proves the efficiency of PBTC method.
