Abstract

The rational function approximation technique (RFAT) is applied to the hybrid finite-element/boundary-integral/multilevel fast multipole algorithm (FE/BI/MLFMA) to acquire wide-band and wide-angle backscatter radar-cross-section (RCS) by complex targets in this paper. The two approaches of utilizing the rational function approximation technique, asymptotic waveform evaluation (AWE) and model-based parameter estimation (MBPE), both have been investigated and compared by theoretical analysis and numerical experiments. The numerical results acquired by the developed computing algorithm of integrating the hybrid FE/BI/MLFMA with the RFAT are presented in the paper, demonstrating that the rational function approximation technique can greatly speed up the hybrid FE/BI/MLFMA to acquire wide-band and wide-angle backscatter radar-cross-section (RCS) by complex targets.
