摘　　要：随着5G基站部署密度的逐年上升,陆续有发射台站出现了卫星信源被干扰的问题。如何实施更高效的防护策略,成为广播电视安全传输管理部门及台站所面临的全新挑战。本文首先对干扰的各要素展开分析,构建了理论计算模型,得出了抑制度指标,并从台站角度出发,提出了切实可行的判断方法、滤波器选择依据以及安装注意事项。文章还建议台站和行业管理部门可以依据有关规则,评估运营商是否存在违规行为,进而展开进一步协调工作,以解决干扰问题。With the increasing deployment density of 5G base station year by year,satellite signal sources have been successively interfered with at radio and television transmitting stations.How to implement more effective protective measures poses a new challenge for both radio and television security transmission management departments and stations.This paper analyzes the elements of interference,establishes a theoretical calculation model,obtains the suppression index,and proposes operational judgment methods from the perspective of stations as well as selection criteria for filters and installation precautions.The article also suggests that stations and industry management departments can assess whether operators are violating regulations based on relevant rules to facilitate further coordination efforts in resolving interference issues.
