| 摘 要： | 提出了电大尺寸目标电磁散射的有限元区域分解计算方法。分析了子区域的有限元解法,建立了区域分解耦合的边界方程,导出了相应的耦合矩阵,并采用了内视法还原了耦合矩阵对称、稀疏的特征,最后研究了不同类型大尺寸目标的雷达散射截面问题并与公开文献结果进行了分析比较。

| Abstract: | An efficient method for solving the problem of EM scattering analysis from targets with electrically large size by DDM with FEM is proposed.The RCS of subarea is calculated by FEM,and the boundary integral equation for domain decomposition coupling is established.The coupling matrix is educed,and inward-looking approach is adopted to transform the coupling matrix into sparse and symmetric.The RCS of kinds of targets with electrically large size is calculated by this DDM,and the results obtained by the method are in good agreement with previously published data. |
