摘　　要：海面对微波散射可用介质散射PMCHW方程描述,针对其离散后阻抗矩阵块的特点,引入电磁互耦迭代方法,结合多层快速多极子(MLFMA)求解,给出计算海面散射等效电流源和磁流源的算法。使用该方法求解分析得到不同起伏程度的海面对微波散射方向性的影响及规律,所得到的规律与文献报道实验测试结论相比较,对比结果验证方法的正确性。EM scattering from sea surface can be described by the integral equation for dielectric （PMCHW）. According to the characteristics of impedance matrix, mutual-coupling iteration and multilevel fast muhipole algorithm （MLFMA） are introduced to solve the integral equation, so that the electric current and magnetic current are calculated. The microwave scattering on different kinds of sea surface situation has been simulated by this method, and the conclusion is compared with the related literatures, and the result shows the correctness of this meothd.
