摘要
本文基于二维频域有限差分(FDFD)法的基本原理,利用Huygens原理,将边界上节点的FDFD方程式中的相关节点加上或减去入射场,将平面入射波引入总场区.计算分析了金属柱阵列的双站RCS,数值结果表明本文方法的正确性和分析复杂目标电磁散射特性的有效性.
This paper has a research on several aspects of it by using two-dimensional Finite Difference Frequency Domain （FDFD） method. Scattering characteristics of complex targets are calculated by using FDFD method, Used the Huygens principle, in the FDFD equations boundary nodes in node plus or minus the incident field, and the plane incident is introduced to the total field area. Computational bistatic RCS of metal pillar array.the numerical results show that the correctness and effectiveness of the method presented in this Dissertation.
