摘　　要：将矩量法(MoM)与渐近波形估计(AWE)技术结合快速计算了目标空域散射特性。通过AWE技术实现快速扫角,提高了计算速度并降低了内存需求。数值结果表明,与传统MoM逐点计算相比,该方法在不失精度条件下大大缩短了计算时间。The Method of Moments（MoM） combined with the Asymptotic Waveform Evaluation（AWE）technique is proposed to analyze the radar cross section（RCS） of targets in spatial domains. The application of AWE enables fast angle sweep analysis. The computational rate is improved and the memory requirement is reduced. The numerical results presented in this paper are compared with the results obtained by the conventional MoM point-by-point calculations. The proposed hybrid technique can greatly reduce the computation time without loss of accuracy.
