摘　　要：无线电导航系统是航空电子系统中非常重要的组成部分之一,在对无线电导航进行在线和总体调试时,往往需要多个地面台和机载设备提供激励信号,大大降低了调试的灵活性。主要以航空电子系统中重要的无线电导航系统(甚高频全向无线电信标、指点信标、自动定向仪和仪表着陆系统等)为对象,采用软件无线电技术,设计并实现机载无线电导航系统集成射频激励器,产生调试过程中所需要的各种激励信号,从而提高无线电导航系统调试的灵活性和效率。Radio navigation system is an important component in modem avionics system. In online and overall debugging of radio navigation system, it always requires cooperation of multiple ground stations and airborne equip- ment, which greatly decreases flexibility during debugging process. Take radio navigation system （including VOR, MKR, ADF and ILS, etc. ） as our research object, an integrated RF exciter for airborne radio navigation system was designed and implomented using software radio technology. Simulation results illustrates that the proposed inte- grated RF exciter can produce kinds of excitation signals required in the debugging process, and greatly improves the flexibility and efficiency of debugging for airborne radio navigation system.
