| 摘 要： | 口径积分-表面积分法是带罩天线远场电性能数值仿真的常用方法,针对该法分析电中大尺寸天线-罩系统远场电性能计算效率过低的问题,提出了基于等效源区域分解的并行口径积分-表面积分算法。开发并在集群系统中实测了基于消息传递并行编程环境(MPI)的并行程序,作为应用计算了某弹载天线-罩系统远场辐射特性。仿真结果表明该并行算法的高效性和准确性。

| Abstract: | The aperture integration-surface integration(AI-SI) method is a common numerical simulation method for the far-fields of the antenna-radome system.Aiming at the low calculation efficiency problem of the electrical large size antennaradome system,a parallel AI-SI algorithm based on decomposed equivalent source region is presented.An algorithm program is developed and tested in the message passing interface(MPI) environment on a cluster system,and the radiation characteristic of the antenna-radome system is calculated.The simulation results show that the proposed parallel algorithm has higher efficiency and precision. |
