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。
The sea surface microwave scattering can be described by the medium scattering PMCHW equation. According to the characteristics of its discrete impedance matrix block, an electromagnetic coupling iteration method is introduced, combined with MLFMA to solve the problem. The sea surface scattering equivalent current source And magnetic current source algorithm. The method is used to analyze and analyze the influence and rule of the sea surface with different fluctuation on microwave scattering direction. The obtained rule is compared with the experimental test results reported in the literature, and the comparison results verify the correctness of the method.
