随着计算机多核技术和计算机群技术的发展和MPI并行技术的应用,使得并行高阶矩量法可以解决复杂大型目标的电磁特性。文中介绍了并行高阶矩量法的基本理论：高阶基函数、并行矩阵填充和并行矩阵求解,并在这些理论的基础上应用其分析舰队的RCS和其它电磁特性来说明这种数值算法的可行性和快速性。“,”The development of multi-cores processors and computer clusters and the application of parallel MPI technique,this makes Parallel Higher Order Method of Moments be able to solve the electromagnetic properties of complex large objects.This paper firstly introduces the basic theory,including High-order Basis Function,Parallel Out-of-Core Matrix filling and Parallel Matrix Solver,then basing on this theory and using them to analyze the RCS and other electromagnetic properties of a fleet,to testify the numerical algorithm is available and fast.
