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。
Radionavigation systems are one of the most important components of avionics systems. When conducting the online and overall debugging of the radionavigation system, multiple ground stations and airborne equipment are often required to provide excitation signals, which greatly reduces the flexibility of debugging. Mainly in the avionics system of important radio navigation systems (VHF omnidirectional radio beacons, pointing beacons, autodetectors and instrument landing systems, etc.) as the object, the use of software and radio technology to design and implementation of airborne radionavigation system integrated radio frequency Actuators that generate the various stimuli required during commissioning to enhance the flexibility and efficiency of commissioning of the radionavigation system.
