摘　　要：通信指挥车的车载电台日益增多,在狭小的空间内,电台之间的耦合干扰迅速加强,车载电台出现同车共址干扰问题,严重时电台的通信会直接中断。针对车载电台存在的共址干扰问题,本文通过多频段复合、将天线在车载平台上进行合理的空间布局如间距和落差等,减小车载全向天线之间的耦合度,保证车载通信系统的高效稳定运行。The number of vehicular radio stations in communication command is increasing,in the small space,the couple between the stations strengthened rapidly,leads to the Co-site Interference(CI)problem of vehicular radio,in the severe cases,radio communication will be directly interrupted.For the Co-site Interference(CI)problem of vehicular radio,in this paper,in this paper,multi-band composite is adopted,and the antennas is rationally arranged on the vehicle platform,such as spacing and vertical drop,the coupling between vehicle omnidirectional antennas is reduced to ensure the efficient and stable operation of vehicle communication system.
