摘要

本文介绍了基于多电平快速多极子算法(FE-BI-MLFMA)的有限元边界积分渐近波形评估(AWE)技术在某一频段雷达截面(RCS)估计中的应用。采用伪导数方法克服了传统AWE实现中使用MLFMA的困难。通过算例验证了该方法的准确性和有效性。

Technique of FE-BI-MLFMA using Asymptotic Waveform Evaluation

This paper introduced the technique of Asymptotic Waveform Evaluation (AWE) applied to the Finite element-boundary integral with Multilevel Fast Multipole Algorithm (FE-BI-MLFMA) for radar cross section (RCS) estimation over a frequency band. A pseudo-derivative method is adopted to overcome the difficulty of using MLFMA in conventional AWE implementation. The accuracy and efficiency of this method are demonstrated by numerical examples.
