民航甚高频地空通信电台干扰与防御措施研究

Research on interference and defense measures of civil aviation VHF ground-air communication station

民航甚高频作为空中交通的重要管理方式,利用甚高频电台进行地空通信,可以帮助航空业务人员确定飞行状态、下达飞行指令,因此民航甚高频地空通信就显得非常关键和重要。但是,由于甚高频地空通信电台运行中面临着许多的干扰现象,比如同频干扰、互调干扰、邻频干扰、杂散辐射干扰,因此需要采用严格的防御措施,尽可能的避免地空通信电台受到干扰影响飞行,保障人们的生命健康安全和财产安全。

The VHF civil aviation is an important management method of air traffic.The use of VHF radio for ground-to-air communication can help aviation business personnel to determine flight status and issue flight instructions.Therefore,civil aviation VHF ground-to-air communication is very important.However,since VHF ground-to-air communication stations face many interference phenomena,such as co-frequency interference,intermediation interference,adjacent frequency interference,and spurious radiation interference,strict defense measures need to be adopted to avoid ground interference as much as possible.The air communication stations are affected by interference and affect flight,which guarantees people’s life,health,and property safety.
