以典型舰船为平台，分析短波大功率天线对舰船敏感位置的辐射危害的变化规律。采用Ship EDF作为仿真工具，得到船体辐射危害的最大区域，通过选取不同位置的天线，得到天线作用于该区域的近场场强大小。由仿真结果可以得出天线数量及分布对船体辐射危害的变化规律，对舰船天线布局具有参考意义。%With the typical ship as a research object, this paper analyzed the change law of radiation hazard caused by large powerful shortwave antennas to the sensitive position of a ship. Using Ship EDF as a simulation tool, the radiated region on the ship was obtained, and by selecting antennas in different positions, the near⁃field strength of the antenna acting on the region was derived. From the simulation results, the radiation hazard to the ship changing with the number and distribution of antennas can be summarized, which is a reference for the antenna layout on the ship.
