高大地物对于中波导航台的无源干扰特性

Passive Interference Characteristics of High and Large Ground Abjects with Medium Wave Beacon

摘要:

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,高大地物是无源干扰的重要组成部分。本文通过对电磁学计算方法的分析,选用矩量法作为研究的数值方法,建立了地物的仿真模型。通过 FEKO软件的仿真,分析了地物无源干扰 的重要特性。

Abstract:

Navigation aviation medium wave radio station electromagnetic environment of the surrounding buildings and allhave related requirements, along with the development of the city, medium-wave navigation station there are big changesin the surrounding environment. After a preliminary investigation it was found that high and large ground abjects is an im.portant part of the passive jamming. In this paper, through the study of the calculation method of electromagnetism, the mo.ment method was chosen as the study of the numerical method, the feature of the simulation model was established, andthrough simulation software FEKO, analyzes the features of passive jamming important features were analyzed.
