摘要
采用基于曲面RWG基函数离散目标表面的感应电流,提取出基函数中的相位信息,同时利用区域分解算法将群目标分解为若干个子区域,利用矩量法计算各个子区域的电流分布和区域间耦合。计算结果表明,利用该方法计算的精度能得到很好的保证,计算的内存需求和计算时间能够大幅度降低,适合于群目标的散射和辐射问题求解。
Electromagnetic scattering from group target with large size has attracted much attention for years.Group target has the properties of large number of objects,large number of unknowns and complex coupling.CRWG basis is used to discretize the induced current for each object with phase extraction.The group target is divided into several groups,and method of moments is used to solve the current of each group and the coupling between the groups.Numerical results show the efficiency and accuracy of this method.CPU time and memory requirement are saved.This algorithm is efficient for analyzing the scattering and radiation of the group target.
