多舰平台间短波电磁干扰比单舰更为复杂,这种复杂性与多舰平台中的舰船数量、舰型以及队形配置密切相关。本文利用多层快速多极子(MLFMM)技术,详细分析了多艘舰船组成列队时的短波电磁干扰特性。预测结果表明,位于列队中部的舰船易受到前后邻舰的短波电磁干扰效应影响,且前舰对后舰产生的短波电磁干扰强于后舰对前舰的同类干扰。原因在于,后者电磁干扰效应还受到了舰船上层建筑遮挡效应的影响。
The multi-ship inter-platform short-wave electromagnetic interference is more complex than that of a single ship. This complexity is closely related to the number of ships, ship types and formation configurations in a multi-ship platform. In this paper, multi-layer fast multipole (MLFMM) technology is used to analyze the short-wave electromagnetic interference characteristics when multiple ships form a queue. The prediction results show that the ships located in the middle of the parade are susceptible to the short-wave electromagnetic interference effect of the adjacent adjacent ships, and the short-wave electromagnetic interference generated by the front ships on the rear ships is stronger than that of the front ships on the front ships. The reason is that the latter electromagnetic interference effect is also affected by the occlusion effect of the superstructure of the ship.
