| Abstract: | Feature extraction on frequency-domain of ship radiated-noise is a key technique for ship-targets recognition.To improve recognition-rate of ship-targets,feature extraction on frequency-domain is studied by using the multiresolution analysis, and fusion of multiscale features on frequency-domain is discussed. The classification recognition for three different classes of ship-targets is measured,and the results show that the extracted features have better classification-effect. |
