基于WINDOWS系统,提出了矩量法(MoM)快速分析导体柱RCS方向图的MATLAB并行计算方案。在新算法中,将计算任务(如:求RCS、阻抗矩阵和它的逆)分配给各个并行计算机,这些计算机利用在彼此间基于局域网搭建的共享空间,进行必要的数据交换,进而完成各自的计算任务。例算都表明所用算法成功地提高了计算速度,可解决个人计算机(PC)因内存偏小不能求解电大物体电磁场问题的困难。 Based on the WINDOWS system, a MoM method for rapid analysis of RCS pattern of conductor bar is proposed. In the new algorithm, computing tasks (such as RCS, impedance matrix and its inverse) are assigned to the parallel computers that make the necessary data exchange by using the shared space set up by the LAN based on each other, so as to complete their respective Calculation task. The example calculations show that the algorithm used successfully improves the computational speed and solves the difficulty of the personal computer (PC) being unable to solve the EM field problem due to the small memory.
