| Abstract: | A matching construction algorithm was developed to improve the anti-jamming performance of ship radar in complex weather condition,identify object effectively,and solve the problem of selecting an optimized wavelet for the radar signal and no real time processing of wavelet multi-resolution.The method could learn from an example radar signal,lock the main power frequency band,and construct optimal scale function and wavelet.The scale function and wavelet had similar frequency component with the example signal.Processing the same kind radar signal with the matched wavelet,the interesting object pattern could be extracted only by one level decomposition and reconstruction.The suitable scale and wavelet which locks the main power frequency band of the learning radar signal are constructed. |
