摘要
针对微波信号在城市近距离传输中所遇到的实际问题,结合电视转播和电视信号传输等实例,利用微波传输及天线相关理论进行了较深入的分析,并根据实际工作经验给出了解决方法,满足了电视转播和电视信号传输的技术要求。
In this paper, the actual microwave signal transmission problems encountered in short distance transmission in urban area are discussed, and examples of television signal relay and transmission are analyzed with the microwave transmission and antenna theories. Solutions to the problems are presented on the basis of the practical work experiences to meet the technical needs of television signal relay and transmission specification.
