微小卫星地面站的电磁环境测试与分析

介绍了预选站址周围电磁干扰源的类型、微小卫星地面站系统的主要技术指标及天线口面处最大允许的干扰电平；测试微小卫星地面站的预选站电磁环境，并对测试结果进行了计算和分析。测试结果表明，点频干扰信号会对卫星地面站数据接收造成影响。最后找出了干扰源所在位置，并排除此干扰信号。

Measurement and Analysis of Electromagnetic Environment around the Micro-satellite Ground Station

In order to ensure that the micro-satellite ground station works well, the electromagnetic environment around the preselected site must be measured. The types of EMI sources around the preselected site, the specifications of micro-satellite ground station and maximum allowable interference level at antenna aperture are introduc.ed. The measurement of the electromagnetic environment for the site selection, including the calculation and analysis of the measuring results, are detailed. The test results indicate that dot frequency interference could have an impact on the data receiving of the satellite ground station. Finally, the location of the interference source is found by surveying the electromagnetic environment, and the interference signal is ruled out through the coordinating with the departments concerned.
