摘要 随着隐身技术的深入发展,以缝隙为代表的弱散射源影响不断增大。文章将等效偶极子法与自适应交叉近似算法相结合以加速阻抗矩阵元素的填充,实现任意电大开缝导体雷达散射截面的快速计算。与矩量法相比,该方法可以大大降低计算时间和内存消耗。 With the development of stealth technology in recent years , the importance of the feeble scattering source ,w hich is represented by the slits ,is increasing .In this paper ,the equivalent dipole-moment(EDM ) method and the adaptive cross approximation (ACA) algorithm are used to fill the im-pedance matrix elements efficiently , thus achieving the fast calculation of the radar cross section (RCS) for any electrically large slotted conductor .Compared with the method of moments(MOM) , the proposed method in the paper could decrease the computing time and save memory dramatically .
