摘　　要：随着5G基站大规模布点,5G信号对C频段广播电视卫星接收站的干扰现象频发。各广播电视卫星接收站纷纷对C频段卫星电视接收系统进行了改造。如何对C频段卫星电视接收系统改造效果做出全面的评估,怎样判断已经实施的改造手段确实有效的解决了5G基站的干扰问题成为下一个关注点。本文通过对一个C频段广播电视卫星接收系统抗干扰改造效果评估的实例进行分析,发现了C频段广播电视卫星接收系统抗干扰测试中需要注意的诸多问题,提出了一种系统评估卫星接收系统抗5G干扰改造效果的方法,为今后各广播卫星接收台站进行改造、评估测试提供了借鉴和参考,对确保广播电视安全播出具有十分重大的意义。With large-scale deployment of 5 G base stations, 5 G signal interferes with C-band radio and television satellite receiving station frequently. Various radio and television satellite receiving stations have reformed C-band satellite TV receiving system. How to make a comprehensive evaluation of transformation effect of C-band satellite TV receiving system, and how to judge that implemented transformation means have effectively solved interference problem of 5 G base station has become the next concern. This paper analyzes an evaluation example of anti-interference transformation effect of C-band radio and television satellite receiving system, finds out many problems needing attention in anti-interference test of C-band radio and television satellite receiving system, and puts forward a method for systematically evaluating the effect of anti-interference transformation of satellite receiving system. It provides a reference for transformation, evaluation and testing of broadcasting satellite receiving stations in the future, which is of great significance to ensure safe broadcasting of radio and television.
