| 摘 要： | 特征基函数的构造是特征基函数方法(characteristic basis function method, CBFM)的关键步骤之一，传统的CBF构造方法(construction of characteristic basis functions, CBFs)是在子区域上应用矩量法(method of moment, MoM)，因此需要消耗大量的计算时间。为降低构造过程的计算量，提高电大目标电磁散射的计算效率，提出了基于高频近似方法的特征基函数快速构造方法，针对边缘效应引入了等效边缘流(equivalent edge currents, EEC)修正，可以在保持算法通用性的同时显著提高包含边缘结构的目标散射计算精度。数值结果验证了方法的正确性及高效性。

| Abstract: | As a key step of characteristic basis function method(CBFM),the construction of characteristic basis functions(CBFs) is an extremely time-consuming procedure,in which the method of moment(MoM) is applied on the sub-block.To reduce the CPU time consumption of the scattering computation for electrically large target,a fast CBFs construction method based on high-frequency approximation is presented.In this method,the equivalent edge currents(EEC) method is introduced to deal with the edge diffraction,which can... |
