摘要:
本文主要针对测量船X频段和S频段测量雷达与导航雷达同频段设备间的电磁干扰问题进行了仿真研究，采用基于时域有限积分的有限元算法和基于MLFMM、高频物理光学和弹跳射线的通用快速电磁计算算法，对测量船X频段和S频段测量雷达的远场辐射方向图、测量雷达与导航雷达耦合度计算等方面进行了仿真计算，并结合设备实测对仿真结果进行了验证。根据仿真结果和实测数据给出了测量雷达的防护措施建议。In this paper, the electromagnetic interferences between tracking radar and marine radar at X-band and S-band are investigated. Far-field radiation patterns of the tracking radars and the coupling between them and the marine radar are calculated and simulated by adopting time-do- main finite element integration algorithm and a general fast electromagnetics algorithm based on MLFMM (multilevel fast multipole), high-frequency physical optics and shooting-and-bouncing- rays method. The results are verified by test and protection measures are suggested.
