天线调节的“圆模型”探究与实践

Research and Practice of"Circle Model"for Antenna Adjustment

在直播和转播中,卫星传输作为重要技术手段而被广电行业广泛运用,在调节卫星接收天线时,会遇到各种情况导致接收信号强度难以满足信号使用需求。文章结合广播电视日常和重要播出保障工作实际,重点探究卫星接收天线调整时遇到的信号弱、区分卫星天线接收主瓣信号和旁瓣信号的情况以及解决方法,旨在为广播电视技术人员提供更加准确地对星手段。

During the period of live broadcasting and rebroadcasting,satellite transmission has been widely used by the radio and television industry as an important technical method.When the satellite antenna is adjusted,the received signal strength can hardly meet the requirements due to the various situations.Considering the important broadcasting guarantee as well as the practical works,this paper focuses on the weak signal,the main lobe and side lobe of satellite receiving antenna when adjusting the receiving antenna,and discusses the situations of easily encountering during the period of adjusting the antenna,so as to provide practical approaches to the technicians of broadcast&television.
