| 摘 要： | 文章利用消息传递协议MPI开发了针对电大尺寸开口腔体单站雷达截面(RCS)的射线弹跳法(SBR)并行计算程序。程序采用按照RCS计算角度间隔分配计算任务的大粒度并行计算方法,取得了较高的并行计算效率,大大减少了电大尺寸开口腔体的RCS计算时间。算例计算结果与文献吻合良好。

| Abstract: | Based on the Message Passing Interface,the paper designs a parallel SBR program used in the RCS calculation of large open-ended cavities.As a big cell parallel calculating method,the calculation tasks are distributed to the processes,evenly spaced,according to RCS calculating angles.The result shows it can achieve a high parallel efficiency and a great reduction in Large Open-ended Cavities'RCS calculating time.The calculating results agree well with the results given by other literature. |
