航空中波无线电导航台站的周边建筑和电磁环境均有相关要求，随着城市的发展，中波导航台站周边环境存在着较大的变化，经过前期的调研发现，中波导航台站周边存在的无源干扰中高压输电线路占据其中的主要部分。通过对电磁学计算方法的研究，选用矩量法作为研究的数值方法，建立高压电输电线路的无源干扰模型，通过FEKO软件的仿真，分析高压输电线路的无源干扰影响，为中波无线电导航台站的环境需求提供理论依据。%The surrounding buildings and electromagnetic environment of navigation station can affect on the medium wave radio station of aviation. With the development of the city,the surrounding environment of the medium wave navigation station has great changes. The preliminary investigation found that the surrounding passive interference from the high⁃voltage transmis⁃sion line can effect on the medium wave navigation station. The calculation method of electromagnetism is studied,for which the moment method is chosen as the numerical method to establish the passive interference model of the high⁃voltage transmission line. The effect of passive interference from high⁃voltage transmission line is analyzed by means of the simulation of FEKO soft⁃ware,which provides the theoretical basis for the environmental requirement of medium wave radio navigation station.
