摘　　要：目标的雷达散射截面(RCS)与照射角度和照射频率都有关系,本文采用渐近波形估计(AWE)技术在角度域和频率域上同时计算任意形状的理想导体的单站RCS,首先用矩量法求解电场积分方程,得到某一角度某一频点的电流密度,通过Pade逼近求出给定角度域内任意角度及给定频带内任意频点的表面电流密度分布,进而计算出给定目标的散射场及雷达散射截面。对数值结果与矩量法逐点求解的结果进行了比较,两者吻合较好,而且提高了计算效率。Target radar scattering cross section （RCS） and irradiation angle and the light frequency have relations. This article base on the asymptotic waveform estimation（AME）technique in angle domain and frequency domain at the same time calculation of arbitrary shape ideal conductor monostatic RCS. First with the moment method is used to solve the electric field integral equation, get a point of a certain frequency point of current density, and through the Pade approximation calculated for a given angle domain at any angle and any within a given frequency band frequency point of surface current density distribution, then calculate the scattering field of a given target and the radar scattering cross section. The results of the numerical results are compared with the method of moment method, which is good in agreement and calculation efficiency is improved.
