Abstract-Synthetic aperture radar (SAR) produces ocean SAR solitary images which include the information of internal solitary waves (ISWs), surface wave, terraininfo and noise. Based on wavelet transform (WT) and bidimensional empirical mode decomposition (BEMD), we give a new algorithm, named wBEMD, to obtain information of ISWs from the SAR images, and apply it on two SAR images to extract ISWs features. The ISWs information layer obtained from wBEMD shows more intact ISW features, from which we retrieve the characteristic width and phase velocity of ISWs and analyse other detailed information. The closeness between the retrieved parameters and observed data verifies wBEMD's practicability.
