摘要 射电望远镜易受地球人工电磁信号干扰,为加强对500 m口径球面射电望远镜(Five-hundred-meter Aperture Spherical radio Telescope,FAST)电磁环境的保护,开展移动基站干扰排查实验,通过对电磁波宁静区内单个及多个基站与FAST的电磁干扰分析,结合望远镜周边传播损耗情况,研究在降低基站干扰的同时保证周边居民通信需求的措施。为减少基站干扰提供了有益建议。 Radio telescopes are vulnerable to the Earth’s artificial electromagnetic signal interference. In order to protect the electromagnetic environment of Five-hundred-meter Aperture Spherical radio Telescope(FAST), the mobile base station interference detection experiment was carried out. By compatibility analyzing the electromagnetic of single and multiple base stations and FAST,and combining the propagation loss around the telescope, the measures to reduce the interference of base stations and ensure the communication demand of surrounding residents are studied, providing useful suggestions for reducing the interference of base stations.
