The multifractal characteristics of ship noise power spectrum are proposed. The multifractal wavelet transform analysis method is studied. The results of multifractal analysis on the Totten-Tau diversity are given and further applied to the ship noise power spectrum. Based on the definition of the ship noise singularity measure, the measured ship noise data processing results show that it can be extracted from the new ship target features
