Doppler Navigation Radar Test System Design

The more advanced and complex the electronic system is, the more difficult it isto undertake fault detection once it does not work well. Especially in maintenance ofairborne electronic systems, rapidly and accurately detecting and repairing the fault isthe first of all. So the automatic detect equipments are urgently needed to improvingrepair efficiency.To meet the requirement of maintaining a kind of airborne Doppler navigationradar, an automatic detect instrument was developed. Based on introducing theprinciple and structure of the radar in detail, this dissertation expounds the method offault isolation and performance test. The design of the important parts of theinstrument is also discussed.
