摘　　要：乘客的无线电子设备通过机载WIFI上网,其信号会对机载通信导航等无线电系统产生电磁干扰。本文分析了机载WIFI信号与机舱外DME接收天线之间的电磁耦合途径,使用CSTMWS仿真WIFI信号对机载导航设备的高频电磁干扰。结果表明,WIFI天线位置及与DME机载接收天线间的路径损耗与距离有密切关系,为有效降低WIFI信号电磁干扰提供参考。Passenger wireless electronic devices access the Internet via on-board WIFI,and their signals can cause electromagnetic interference to radio systems such as airborne communication and navigation.This paper analyzes the electromagnetic coupling path between the airborne WIFI signal and the DME receiving antenna outside the cabin,and uses CST MWS to simulate the high frequency electromagnetic interference of the WIFI signal to the airborne navigation equipment.The results show that the position of the WIFI antenna and the path loss and distance between the DME airborne receiving antenna are closely related,which provides a reference for effectively reducing the electromagnetic interference of the WIFI signal.
