摘　　要：超宽带(ultra-wide band,UWB)技术的迅猛发展使UWB设备与现存无线通信系统间兼容性问题的研究越来越重要,UWB信号对其带内及带外不同无线通信系统存在着不同程度的干扰作用。在对战术空中导航系统(Tactical Air Navigation,TACAN)的信号特征进行分析的基础上,结合UWB路径损耗模型,从平均功率的角度讨论了脉冲UWB信号对TACAN系统的干扰情况,为进一步的研究提供了借鉴与参考。The development of UWB technique makes the coexistence of the UWB equipment and the existing radio communication systems more and more important. The interference of UWB varies with the radio communication systems in and out of its band. Based on a simple analysis of the characteristic of TACAN signal, the interference of UWB signal to TACAN receiver is discussed from the aspect of average power by using the UWB path loss models, which may offer reference to further study.
