摘要
电磁干扰一直是影响客机正常起飞和降落的关键性问题之一。分析地基天线对大型飞机近场的影响可以作为机场附近天线布局的指导。然而由于计算机存储资源的限制,难以对复杂的电大尺寸目标进行精确仿真。随着计算机软硬件技术的不断发展,计算机集群的大规模并行计算技术使得这一问题得到解决。本文基于并行高阶矩量法,利用国产计算机平台中的10240个CPU核对大型飞机周围电磁环境受地基天线的影响进行了仿真分析,验证了大型飞机近场分布精确计算的可行性。
Electromagnetic interference has been one of the critical issues on the normal takeoff and landing for the aircraft. The analysis of the effect of ground antenna on large aircraft near-field can serve as a guide for the antenna layout. However, the limit of computer storage resources makes it difficult to simulate complex electrically large target accurately. With the development of computer hardware and software technology, large-scale parallel computing technology makes it possible to be solved. Based on the parallel higher order Method of Moments, in this article, using 10240 CPU cores on the domestically-made supercomputer platform, the influence of a ground antenna on the electromagnetic characteristics of large aircraft around is simulated, which indicates it is feasible to analyze the near-field distribution of large aircraft accurately.
