高阶叠层渐近相位基函数结合快速多级子分析电大物体散射特性
Analysis on electromagnetic scattering features of big objects in combination with MLFMA and higher-order hierarchical asymptotic phase basis functions
摘要
Abstract
In this paper,since the relations of the incident wave and surface⁃current,the application of asymptotic phase (AP)in the higher⁃order hierarchical basis functions(HO⁃RWG)is derived,and applied in method of moment(MOM). The electromagnetic scattering features of electrical⁃large targets are analysed in combination with multilevel fast multipole algorithm (MLFMA). Compared with the higher⁃order hierarchical basis functions and zero⁃order phase basis functions(AP⁃CRWG),the unknown quantity in this method can be cut off more in the same computational precision Thereby,much of memory and time can be saved. Numerical examples in radar cross section calculation demonstrate the accuracy and efficiency of the proposed method.关键词
