目标的雷达散射截面(RCS)与照射角度和照射频率都有关系,采用渐近波形估计(AWE)技术在角度域和频率域上预测任意形状的理想导体的单站RCS,通过Padé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。
The radar cross section (RCS) of the target is related to both the illumination angle and the illumination frequency. The asymptotic waveform estimation (AWE) technique is used to predict the single-station RCS with ideal conductor of arbitrary shape in the angle domain and the frequency domain, Given the angle of an arbitrary angle within the given frequency band and any frequency of the surface current density distribution, and then calculate the given target scattering field and radar cross section. The numerical results and the method of moment method are compared point by point, the agreement between the two is good, and the computational efficiency is improved.
