FA36甚高频业务承载研究

摘要

FA36 is one of access equipment of telecommunication used in the civil aviation air trafifc control system, which can be used for carrying radar, very high frequency (VHF), air traffic telegraph, VCS(Voice Communication System) and other air traffic control service. This paper focuses on the “echo” problem which occurs when the VHF service transports over FA36, launches the analysis, determine the cause, and puts forward the treatment method in the actual application scenarios. Moreover, the derived “endings” problem is also analysed and saluted. This paper provides the optimized solution of the VHF Service transport over FA36, which can provide the reference for the industry.%FA36是民航空管系统采用的传输接入设备之一，它可以用于承载雷达、甚高频（VHF）、航空电报、管制移交电话等空管业务。文章针对FA36承载甚高频业务发生的“回音”问题展开分析，确定原因，结合具体应用场景提出处理方法，同时对衍生的“尾音”问题也进行了分析和解决。提供的FA36甚高频业务承载的优化应用方案，可为业内同行提供参考。
