Multi-feature SAR (Synthetic Aperture Radar) oil spill detection method

The invention discloses a multi-feature SAR (synthetic aperture radar) oil spill detection method, which comprises the following steps of: firstly, designing a novel polarization feature combination by considering the physical deviation of a scattering mechanism of Bragg scattering, and effectively inhibiting the influence of noise while effectively identifying an oil film and an oil-like film; on the basis, a detection result of the oil spill area is obtained based on an oil spill area extraction model; at the moment, in order to further overcome the phenomena of unsmooth boundary and internal void in the result, a contour regularization boundary correction strategy based on coarse segmentation guidance is provided, so that a final oil spill detection result is obtained. According to the method, the problem that oil film interference factors such as weak damping similar substances and bio-oil films existing in a complex sea surface environment cause interference on detection of the oil ...
