摘　　要：中国近期建造和预研了若干大口径单天线和阵列射电望远镜。为了使射电望远镜得到最优的电磁环境,需要将望远镜台址选择在偏远地区,并持续进行电磁环境的保护。西藏自治区山南市山脉众多,海拔高差值好,存在潜在优秀的射电望远镜台址,通过踏勘后,对候选台址进行了科学化的电磁环境测试。文章论述了电磁环境测量系统的组成和系统参数,数据分析和处理方法,使用电磁环境测量设备对山南射电望远镜候选台址进行了测试,并根据测量数据分析了望远镜侯选台址附近的射电干扰情况。Several large-aperture single-antenna and array radio telescopes have been built and prefabricated in China recently.To obtain the optimal electromagnetic environment for radio telescopes,it is necessary to select the telescope site in a remote area and continue to protect the electromagnetic environment.There are many mountains with a good range of differences in altitude in Shannan,which could be potentially excellent radio telescope sites.After the field survey,a scientific electromagnetic environment monitor was carried out on the candidate site.In this paper,the constituents and system parameters,data analysis,and processing methods of the electromagnetic environment measurement system are discussed,and the candidate site of Shannan radio telescope using electromagnetic environment measurement equipment is tested,moreover,the radio interference near the candidate site of the telescope according to the measurement data is analyzed.
