摘要 将渐近波形估计(AWE)技术结合等效偶极子(EDM)法应用于任意三维导体目标宽带雷达散射截面(RCS)的快速计算.首先利用等效偶极子法实现阻抗矩阵的快速填充及其多阶导数矩阵的快速计算,并利用内外迭代近场预处理技术加速矩阵方程的求解,进而应用渐近波形估计技术实现宽带雷达散射截面(RCS)的快速计算.数值计算表明:本文方法在保证计算精度的前提下,提高了计算效率. Asymptotic waveform evaluation (AWE) technique in conjunction with equivalent dipole-moment (EDM) method is applied to obtain radar cross section (RCS) of an arbitrarily shaped three-dimensional (3-D) perfect electric conductor (PEC) over a frequency band. EDM method is used to achieve fast filling of impedance matrix and more derivative matrices. Inner and outer iterative near field preconditioning technique is used to solve matrix equation. Wide-band radar cross section is achieved by using AWE technique. Numerical results show that the computational efficiency is improved significantly with ensuring accuracy.
