摘要

本文首先对用于矩量法(MoM)频带响应求解的传统波形渐进估计(AWE)技术进行了深入分析,得出传统AWE技术有可能产生病态的Pade逼近系数矩阵这一重要结论.由此引用了良态波形渐进估计(WCAWE)技术,并用于快速求解任意形状三维导体的宽频带雷达散射截面.数值结果表明:采用WCAWE技术,计算效率明显提高.

Abstract

Traditional asymptotic waveform evaluation (AWE) with Moment of Method (MoM) for frequency response fast calculations is analyzed deeply.And an important conclusion is drawn:ill-conditioned coefficient matrix of Pade approximation may be resulted from traditional AWE.Well-conditioned asymptotic waveform evaluation is thus introduced.And an implementation of WCAWE is presented for obtaining the frequency response of the Radar Cross Section (RCS) of arbitrarily shaped three dimensional perfect electric conductor (PEC) bodies.Examples given demonstrate that the numerical computation efficiency is improved drastically using WCAWE.
