“…This mode was named hybrid-polarity (HP) or compact-polarimetric (CP) mode. In addition, the polarimetric information given in the HP (CP) mode is in some cases reported to be close to that of FP SARs (see, e.g., [7]- [10]). The HP mode belongs in the DP SAR group, with wider swath and equal spatial resolution or improved spatial resolution and equal swath compared to the conventional FP SARs.…”

“…This configuration is already integrated in current satellite missions, such as RISAT-1 and ALOS-2, and will also be incorporated in several upcoming spaceborne SARs. Recognizing its great potential for oil spill detection identified in [10] [11], we choose HP as a comparing system to FP SAR in this work. The fundamental quantities measured by a polarimetric SAR system are the complex backscattering terms S ij .…”

“…In addition, a similar model is also necessary when evaluating polarimetric features from the FP covariance matrix. Therefore, in [10], the authors suggested to use the two-scale Bragg for the HP mode. This model is similar to the tilted Bragg model in terms of containing two scales of the surface roughness, namely the small-and the large-scale roughness.…”

“…This model is similar to the tilted Bragg model in terms of containing two scales of the surface roughness, namely the small-and the large-scale roughness. The authors of [10] used the two-scale model by first simulating the HP scattering vector followed by a projection to the circular basis. The matrix (S) of scattering coefficients denotes the Sinclair scattering matrix.…”

Abstract-Oil spill detection using a time series of images acquired off Norway in June 2015 with the Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) is examined. The relative performance of a set of features derived from quadpolarization vs. hybrid-polarity modes in detection of various types of slicks as they evolve on a high wind driven sea surface is evaluated. It is shown that the hybrid-polarity mode is comparable to the full-polarimetric mode in its ability to distinguish the various slicks from open water for challenging conditions of high winds (9-12 m/s), small release volumes (0.2 -0.5m3 ), and during the period 0-9 hours following release. The features that contain the cross-polarization component are better for distinguishing the various slicks from open water at later and more developed stages. Although these features are not available in the hybrid-polarity mode, we identify alternative features to achieve similar results. In addition, a clear correlation between the results of individual features and their dependence on particular components within the two-scale Bragg scattering theory is identified. The features that show poor detectability of the oil slicks are those that are independent of the small-scale roughness, while the features resulting in good separability were dependent on several factors in the two-scale Bragg scattering model. We conclude that the hybrid-polarity mode is a viable alternative for SAR-based oil spill detection and monitoring that provides comparable results to those from quad-polarimetric SAR.
