Transient feature extraction and discrimination of wideband echos based on wavlet transform

  • The performance of wavelet transform on extracting edge of underwater sonar echoes is investigated.The theoretical and experimental results show that WT has strong ability to characterize different edges with high noise immunity.A method to extract edge features of wideband echoes using discrete dyadic wavelet transform is proposed,and experimental results based on real data demonstrate the efficiency of the method.
