摘　　要：Identification of an oil spill is additionally essential to evaluate the potential spread and float from the source to the adjacent coastal terrains.In such manner,usage of Synthetic Aperture RADAR(SAR)information for the recognition and checking of oil spills has gotten extensive consideration as of late,because of their wide zone inclusion,day-night and all-weather capabilities.The present examination studies an oil spill occurred in the Al Khafji region by applying Sentinel 1 SAR-C images.Al Khafji is on the borderline between Saudi Arabia and Kuwait in the Persian Gulf and it is detected as an unbiased zone.Al Khafji region can possibly deliver in excess of 7472.403 m³barrels of oil for every day(m³/d).Approaches dependent on multi-sensor satellite images examination have been produced for distinguishing oil spills from referred to common leaks just as oil slick procedures.In this paper,one of these techniques is associated with Sentinel 1 images of a known region of natural oil leakage and of an ongoing oil slick incident in Al Khafji zone.The Synthetic Aperture Radar(SAR)is perceived as the most significant remote sensing apparatus for the ocean and ocean waters oil slick examination,recording,documentation and propagation.Specifically,this paper examines oil spills recognition in the Persian Gulf surveyed by utilizing Sentinel-1(SAR-C)imageries.Results demonstrated the significance of the VV polarization of the Sentinel-1 for recognizing oil-spills just as the diminished utility of the VH polarization in this sole circumstance.
