Research on Detection Oil Spill Information Based on Polarization Decomposition

How to extract oil spill information accurately with full polarization SAR data is the current problem, Polarization decomposition is one of the effective ways to improve the accuracy of oil spill information detection. Based on the polarization decomposition parameter entropy H, scattering Angle and anti-entropy A, this paper analyzes polarization decomposition parameters and carries out extraction of oil spill information. In the light of the similar characteristics of oil spill in entropy H and scattering angle parameters, platform and ship is analyzed, which bring the false of oil spill, and various indexes are constructed. From scattering mechanism and test results, established the index of the oil spill information extraction, combined with the oil spill features, this paper proposes a simple and effective information automatic extraction method of oil spill, The accuracy is about 71.4%, which can meet the needs of oil spill operation monitoring.
