| Abstract: | In view of the characteristics of ship-radiated noise signal,a method of wavelet transformation for ship-radiated noise de-nosing is proposed.The de-noising experiments of ship-radiated noise signals are made by MATLAB,and different wavelet base and threshold value are selected,and then some simple analysis and comparison on the results are given.The results prove that we can get a very effective outcome by the method of wavelet transformation if the adaptive wavelet base and threshold value are chosen. |
