APPLICATION OF THE WAVELET TRANSFORMATION TO THE ACTIVE DAMAGE DETECTION OF COMPOSITE MATERIAL

Based on the limitation of classical signal processing methods in case of nonstationality, the modules maximum evolution behavior of singular and random noise in multiscale space was analyzed using the WT. A simulation AE signal was processed. And an effective algorithm was presented to obtain the useful signal about the place information from the simulation signal. It shows the nice future of the application in the active damage detection of composite material.
