| 摘 要： | 针对三维复杂电大尺寸金属目标,在传统MoM-PO混合法的基础上,引入基于射线密度归一化(RDN)概念的射线弹跳法(SBR),计算电大PO区域内部的多次反射影响,从而得到一种新的MoM-SBR/PO混合方法,该方法区别于大部分改进的MoM-PO混合法对PO区域内多次反射贡献的处理,避免了迭代物理光学法涉及的多次矩阵相乘问题.与其它几种方法进行比较,结果显示吻合较好.

| Abstract: | For electromagnetic scattering of 3-D complex electrically large conducting targets,a new hybrid method MoM-SBR/PO is presented to calculate multi-reflection contribution in the PO region, by introducing SBR method that based on Ray-Density Normalization (RDN). Complex matrix multiplication procedure is avoided in this method. Finally, numerical results are presented and compared with reference MoM2D solutions in order to illustrate accuracy and efficiency of the proposed approach. |
