摘 要:卫星传输是广播电视技术的主要标志之一,卫星信号在传输过程中,存在5G信号、机场雷达等干扰问题。对卫星广播电视频段的干扰源进行了分析,以中国广电辽宁广电的卫星接收天线抗干扰设计为例,从寻找干扰波的辐射死角、抗干扰卫星天线的选择、高频头的选择、安装屏蔽网等多种方案的组合使用,对抗干扰技术的应用效果进行研究。Satellite transmission is one of the main symbols of modern radio and television technology,but there are interference problems such as 5G signal and airport radar in the process of satellite signal transmission.In this paper,the interference sources of satellite radio and television frequency band are analyzed.Taking the anti-interference design of satellite receiving antenna of China Radio and television Liaoning network as an example,the application effect of anti-interference technology is studied from the combination of finding the radiation dead angle of interference wave,the selection of anti-interference satellite antenna,the selection of tuner,the installation of shielding network and so on.
