Ship and Sea-Ice Discrimination Using Sub-Spectra Strategy and Single Polarimetric Sar Imagery

This paper presents a new approach for the study of ship discrimination in complex sea ice ocean environment using single polarimetric synthetic aperture radar data and sub-spectra strategy. A statistic descriptor related to the signal coherence in the Time-Frequency domain, is proposed to enhance the ship/background contrast and improve discrimination capabilities. Using RADARSAT-2 single polarization data over complex sea ice scenes in Arctic ocean, experimental results demonstrate the efficiency of this method in terms of ship location retrieval and response characterization.
