针对飞机大型通信导航识别系统的功能和主要性能原位检测的需要,利用软件无线电和综合化技术,设计一套便携式对通模拟器,通过无线和有线方式实现对通信导航识别系统的各项功能和主要性能的室外测试,还可为通信导航识别系统内部故障定位提供专用的信号和检测手段。该便携式自动测试系统可与被测系统互通,并具有环境适应性好、综合性强和重量轻的特点。
Aiming at the need of in-situ detection of the function and main performance of aircraft large-scale communication and navigation recognition system, a set of portable pair-pass simulators are designed by using software radio and integrated technology to realize the functions of communication and navigation identification system through wireless and wired methods And the main performance of the outdoor test, but also for communication and navigation system to identify internal fault location to provide a dedicated signal and detection methods. The portable automatic test system interoperability with the system under test, and has good environmental adaptability, comprehensive and light weight characteristics.
