Intelligent Fault Diagnosis of Radar Printed Plates Based on Rough Set Hybrid System

DAI Jianpeng1,WEI Zhensheng1,WANG Chunping1,QIU Feng2 (1.Ordnance Engineering College,Shijiazhuang050003,China;2.Repairing Station of Ordnance and Radar of Shenyang Military Region,Shenyang110141,China)  
In the new type of radar,there are many complicated replaceable board-level circuits.To diagnose the board-level circuit fault rapidly,we put forward a hybrid system of rough set,neural network,and expert system for fault diagnosis of radar equipment.The working principle of the hybrid system in board-level circuit fault diagnosis of radar was introduced.A platform of fault sample training and fault diagnosis was established.An example was trained and actually diagnosed with the hybrid system of rough set-neural network-expert system on this platform.The diagnosis result showed that the fault diagnosis method is superior to others and can accurately locate fault,which can solve the problem in replaceable board-level circuit diagnosis of radar.
