摘要
为了提高电大尺寸复杂目标散射的计算效率,分析了加法定理和快速远场近似理论,并将其和多层快速多极子方法相结合,从而降低了计算复杂度.文中结合某型导弹的设计要求建模仿真,得出的结论可以反映实际的变化趋势,且该方法运算速度快,不受目标尺寸约束,完全可以满足工程分析的需要.
In order to accelerate the solution procedure of electromagnetic scattering problems, addition theorem and fast far-field approximation theory are analyzed and applied to multilevel fast multipole algorithm, the computation complexity is greatly reduced. Based on a certain type of missile, modeling and simulation are carried out, and the simulation result is close to the actual result. The computing speed is improved and no target size constraints, and can be applied to the actual engineering analysis.
