摘　　要：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。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.
