Abstract

We propose an accurate and efficient method for the wideband analysis of a finite periodic array near an object. It elegantly combines the merits of the modified simplified subentire domain (SSED)-characteristic basis function method (CBFM) and the improved frequency-independent reaction (FIR). It constructs the SSED basis functions on the array cell and CBFs on the object and, thus, obtains the SSED-CBFs-based reduced matrix equation. The improved FIR accelerates the computation of the impedance matrices at each frequency. Our new method keeps high accuracy in the numerical examples while greatly reducing the total CPU time.

基于改进SSED-CBFM和改进FIR的目标附近有限周期阵列宽带RCS分析

我们提出了一种精确而有效的方法来分析靠近目标的有限周期阵列的宽带。它巧妙地结合了改进的简化亚全域-特征基函数法和改进的频率无关反应法的优点。在阵列单元和对象的CBFs上分别构造了SSED基函数和CBFs，得到了基于SSED-CBFs的约简矩阵方程。改进的FIR加快了各频率阻抗矩阵的计算速度。新方法在保证数值算例精度的同时，大大减少了总CPU时间。

期刊介绍： IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
