摘要
VHF通信是构成船一岸移动通信的技术手段之一,是水上通信(信息)网的重要组成部分.本文讨论了它的设计特点,总体要求,服务区域、场强及系统余量的计算,天线性能及收发隔离度计算等几个主要问题.
The VHF communication system is one of the technical means that compose the mobile ves-
sel-shore service,and is an important part of the water communication (information) nets. In this
paper,the following main problems are discussed: the design characteristics and overall require-
ment of the system,the performance of antennas,and calculation of service area,field intensity,
system margin and receiving-transmitting isolated level.
