AbstractPolarimetric information is investigated for ship detection and characterization at operational satellite SAR incidence angles (20° to 60°). The polarization anisotropy introduced in [20] is used for Optimal information extraction. It is shown that fully polarimetric information permits a significant improvement of ship-sea contrast at relatively calm wind conditions, in comparison with the conventional (scalar) one channel polarization (HH, VV, or HV). In rough sea conditions, the effectiveness of polarimetric tools can be significantly degraded. Ship characterization is also investigated using the symmetric scattering characterization method (SSCM), which was introduced in [21]. The SSCM method appears to be very promising for ship identification. Identification of ship targets with significant symmetric scattering is shown to lead to accurate pitch measurement, under certain conditions.
