Combined Fault Diagnosis of Radar Based on PCA and Neural Network
Jing Tao · Science Technology and Engineering · 2009
To overcome the shortcomings of single diagnosis method,a combined fault diagnosis approach based on principle component analysis (PCA) and neural network (NN) is presented.The approach use PCA to monitor radar state and identify fault location by variable contributions. At last,neural network is utilized for fault diagnosis. Case study of the proposed method is presented for radar,and the feasibility of method is analyzed.
