摘要 宽带宽角特性是电磁研究领域具有重要意义的课题。文章旨在将自适应修正特征基函数法(AM-CBFM)与基于模型参数估计(MBPE)的技术结合来构造一种快速分析三维目标体宽带宽角电磁特性的混合算法——AMCBFM-MBPE。其中AMCBFM基于对目标体分块,并充分考虑了各分块间耦合度的不同,块间耦合激励通过一系列的系数来修正,收敛判据运用各阶基函数所得的电流来确定。而MBPE基于有理函数插值法。AMCBFM-MBPE技术通过自适应采样后,只需要得到采样点的信息即可求得区间上的电磁特性。比逐点计算目标体电磁特性的传统方法明显减少了采样点的数目。数值结果显示,该混合方法具有精度高、计算时间少、不需要多余存储空间等优点。 Abstract： Wide-band ＆ wide-angle characteristic is a significant topic in electromagnetic field. In this paper, a hybrid method is constructed by the AMCBFM combined with MBPE, which is used to analyze the wide-band ＆ wide-angle electromagnetic scattering characteristic. In AMCBFM, the objects are portioned into blocks, and the coupling excitations are modified by a series of coefficients due to the difference of mutual effect between the distinct blocks. The convergence criteri- on is built via the current density derived by various levels basis functions. And the MBPE is based on the rational function interpolation. An adaptive sampling algorithm is applied to AMCBFM-MBPE to ensure the number of sampling points. Com- pared with the conventional one-by-one-point computational method, AMCBFM-MBPE can derive the characteristic curve in the solved region just via the sampling points information. The results show that the hybrid method can save more computa- tional time and has advantages of satisfied precision and no more excrescent memory space in the computational processing.
