It is possible to construct three features from the quad-pol coherency matrix of the X-Bragg scattering model, two that are independent of the relative permittivity, and one that is independent of the surface roughness. In this study we test these three features on Radarsat-2 and SIR-C data containing oil spill and look-alikes, in order to investigate the properties of these features for oil spill detection. We find that the features may distinguish oil from water, but are less sensitive to biogenic slicks and other look alikes. This useful for for operational oil spill detection.
