Marine Oil Slick Detection Using Improved Polarimetric Feature Parameters Based on Polarimetric Synthetic Aperture Radar Data

Marine oil spill detection is vital for strengthening the emergency commands of accidents and repairing marine environment after a disaster. Polarimetric Synthetic Aperture Radar (Pol-SAR) can obtain abundant information targets by measuring their complex scattering matrices, which conducive to analyze interpret mechanism slicks, look-alikes, seawater realize extraction slicks. The polarimetric features quad-pol SAR have now been extended detection. Inspired this advancement, we proposed set improved feature combination based on entropy H anisotropy A12–H_A12. objective study was improve distinguishability between background seawater. First, capability H_A12 observed be superior than that obtained using traditional H_A combination; therefore, it adopted as an alternate strategy latter. Second, H(1 ? A12) enhance randomness target, outperformed remaining types parameters in different scenarios, including respect relative thickness slicks evaluations comparisons showed indicate slick effectively suppress sea clutter look-alike information.
