摘　　要：民用航空管制员大多使用甚高频地空通信系统实现与机组之间的语音通信。当多个甚高频设备同时发射时,在重叠区域往往会产生差拍干扰,导致机组无法收到清晰有效的语音信息。民航通信设备维护部门通过为台站设置不同的频偏来解决这个问题。Most civil aviation controllers use VHF ground to air communication system to realize voice communication with aircrew.When multiple VHF equipments transmit at the same time,there will be beat interference in the overlapping area,which leads to the failure of the crew to receive clear and effective voice information.The maintenance department of civil aviation communication equipment solves this problem by setting different frequency offsets for stations.
