舰船天线辐射仿真计算研究

内容简介：预设计是实现舰船总体电磁兼容性先进的设计方法,而天线辐射效能的仿真计算是预设计手段之一。针对舰船天线布置及设计需求,提出一种天线的建模方法,并根据该方法进行天线辐射效能的仿真计算。首先运用FEKO软件对舰船的一种组合天线进行三维空间参数建模和电激励参数建模,然后根据舰船不同的工作状态进行仿真计算,预测该工作状态下天线的辐射效能,最后对仿真计算结果进行对比分析。为舰船天线设计提供定性的建议和定量的数据,为舰船天线优化布置提供了参考依据。

Abstract：Pre-designing is an advanced design method for realizing ship collectivity EMC, and antenna radiation efficiency emulation calculation is one of the pre-designing methods. This research aims at the ship antenna arrangement and the design demand, and preliminarily establishes a modeling method of antenna, then calculates the antenna radiation efficiency by this method. Firstly, this research set a ship combined antenna model of three-dimensional space parameter and electricity source parameter. Secondly, this research emulation calculated according to ship's different operation conditions, and forecasted antenna radiation efficiency in this operation condition. Lastly, this research compared and analyzed the emulation results. This research provides qualitative suggest and quantification data for ship antenna design, and provides reference for ship antenna majorization arrangement.
