摘要
甚高频通信邻道串扰一直以来都是困扰航空管制地空通信的一个难题,作为空管设备保障部门,须寻求有效的措施来抑制邻道串扰。本文以重庆江北机场机坪塔台出现甚高频通信邻道串扰问题为例,介绍了邻道串扰的定义,分析了邻道串扰产生的机理,提出了有效抑制邻道串扰的解决方案,并应用于工作实践,基本上解决了机坪塔台甚高频邻道串扰的问题。增加收发信机之间的系统隔离度,可以有效解决甚高频通信邻道串扰问题。
The adjacent channel interference of VHF communications has always been a difficult issue in the field of air traffic control.As an ATC equipment support department,it is necessary to find effective measures to suppress adjacent channel interference.Through the problems in the apron tower of the Chongqing airport,the definition of adjacent channel interference of VHF communications is introduced,and the mechanism of adjacent channel interference is analyzed.The measures to suppress the adjacent channel interference has been proposed,and the practice shows that these methods are effective.Increasing the system isolation between transmitter and receiver can effectively solve the problem of adjacent channel transmitter and receiver in VHF communication.
