| Abstract: | Based on wavelet transform, a new method of detecting ship noise in white noise is proposed. The detection statistics based on the wavelet coefficients is given and the performance of the detector is evaluated. Comparing with the energy detector and the matched filter, computer simulations show that the proposed approach is effective. |
