无线电电磁环境的优劣会影响无线电监测站接收系统的灵敏度,因此,定期对监测场地周围的电磁环境进行全面、系统的监测显得十分必要.本文针对这个问题搭建了实验链路,设计了实验步骤完成了监测场地电磁环境采集测试.测试结果显示,福建监测站测向天线场受周边不符合国标规定的路桥工程影响,出现短时干扰和等间隔脉冲干扰,电磁环境出现恶化.
無線電電磁環境的優劣會影響無線電鑑測站接收繫統的靈敏度,因此,定期對鑑測場地週圍的電磁環境進行全麵、繫統的鑑測顯得十分必要.本文針對這箇問題搭建瞭實驗鏈路,設計瞭實驗步驟完成瞭鑑測場地電磁環境採集測試.測試結果顯示,福建鑑測站測嚮天線場受週邊不符閤國標規定的路橋工程影響,齣現短時榦擾和等間隔脈遲榦擾,電磁環境齣現噁化.

Sensitivity of radio monitoring station receiving system will be affected by the quality ofradio electromagnetic environment, so the periodic electromagnetic environment test is necessary. Aiming at the problem, this paper designed an experimental link and the experimental steps to finish the Electromagnetic environment acquisition test and then analyzed the result. The test results showed thatsince the effect of illegalroad and bridge project nearby,short-term interference and regular-pulse interference has been discovered at direction finding antenna field, Fujian monitoring station, and the electromagnetic environment has deteriorated.
