| Abstract: | The idea of fast multipole algorithm (FMA) was presented from a heuristic viewpoint.The steps of FMA were analysed by 3D conductor objects,and the basic idea of MLFMA was presented.Next,the RCS of conductor sphere was calculated by FMA,and pointed out applied prospect of the method,which was greatly superior over MM in the calculation speed and memory requirement by analysis,and was suit for solution to electrical large object's scattering. |
