摘要
用启发式方法给出了FMA的基本思想 ,并以三维导体目标为例分析了FMA的步骤 ,也给出了MLFMA的基本思路 .然后用该方法计算了导体球的RCS ,指出该方法的应用前景 .通过分析表明该方法在计算速度和存储要求方面比矩量法有明显优势 ,适合于在现有计算机条件下求解电大尺寸目标的散射问题 .
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.
