摘要
探讨了机载应答设备对GPS-L5接收机的电磁干扰状况。通过机载试验,测量了L5波段电磁频谱,分析测量数据后得到若干能量谱图。并通过与远距离监控装备/塔康导航设备(DME/TACAN)干扰信号的比较得到应答设备比它们具有更小干扰的结论。
This is an information paper on the measured interference from transponder to onboard GPS-L5 receiver. The onboard frequency spectrum in L5/E5 band is measured. After analyzing we got figures of power spectrum. It is estimated to be less harmful than that of DME/TACAN replies from ground by comparing.
