摘要
在矩量法的基础上 ,应用空间分解技术将二维电大导体目标剖分成若干子区域 ,考虑子区域间的耦合 ,通过累进迭代法计算出目标表面电流 ,然后结合渐近波形估计技术计算了二维电大导体目标的宽带雷达散射截面。数值计算表明 :计算结果与矩量法逐点计算结果相吻合 。
Based on the method of moments (MoM), the two-dimensional electrically large conducting object was divided into several small regions by employing spatial decomposition technique. Considering the coupling effect between sub-regions, the surface currents were calculated with the progressive iterative numerical method, and the wide-band RCS was obtained by asymptotic waveform evaluation technique. The numerical results are in good agreement with that achieved by the method of moments, and the proposed scheme exceeds considerably MoM in the computational efficiency.
