摘要
基于物理光学法及物理绕射理论,应用专用舰船电磁仿真软件Ship-EDF,定量计算分析舰船典型结构对天线辐射性能的影响。分析研究舰船结构对天线反射或散射所引起天线辐射方向图的畸变情况,重点讨论天线上舰前后方向图特性对比和舰船桅杆对天线辐射特性的影响。
A new method is presented to calculate the radiation performance of the antenna mounted on the ship based on the physical optics and physical diffraction,and analyse the impact that ship structure to the antenna quantitatively by the Ship- EDF which is tailor made for the ship electromagnetic simulation.It is analyzed the antenna radiation pattern distortion caused by the ship structure and the antenna pattern comparison between in free space and installed on the ship.
