Over past few years Synthetic Aperture Radar(SAR) has received a considerable attention for monitoring and detection of oil spill
due to its unique capabilities to provide wide-area surveillance and day and night measurements, almost independently from
atmospheric conditions. The critical part of the oil spill detection is to distinguish oil spills from other natural phenomena. Stokes
vector analysis of the image data is studied to estimate the polarized circular and linear components of the backscatter signal which
essentially utilize the degree of polarization(m) and relative phase (δ) of the target. In a controlled oil spill experiment conducted at
Norwegian bay during 17th to 22nd June 2014, RISAT-1 hybrid polarimetry images were utilized to study the characteristics of oil
spill in the sea. The preliminary results obtained by using polarimetric decomposition technique on hybrid polarimetric data to
decipher the polarimetric characteristics of oil spills from natural waters are discussed in the paper.
