An analysis of the polarimetric scattering properties of oil-covered waters is conducted using the classic Poincaré ellipticity parameter chi (${bm {chi} }$) and the degree of polarization (${bm {m}}$) from the Stokes parameters of hybrid polarized mode synthetic aperture radar (SAR). Oil spills reduce ${bm {m}}$ for all four cases considered in this study. However, for the natural oil seep case considered, ${bm {chi} }$ has a change in signs, comparing oil-covered waters with the “clean” ocean surface. The ${bm {chi} }$ sign reversal is basic for “sign difference oil spill detection methods.” However, a problem is that the oil spill related to the deep water horizon (DWH) disaster did not exhibit a reversal in ${bm {chi} }$ signs, comparing the “clean” ocean surface to the area contaminated by crude oil. The scattering mechanism related to the oil seep is different from that of the DWH oil spill; the former is dominated with even bounce scattering and the latter is dominated by Bragg scattering, similar to that of the clean oil-free ocean surface, in the imaging area. |
