Abstract
In the present paper, Equivalent Number of Looks (ENL) are estimated for quad polarization RADARSAT-2 SLC data, and used to define a detection method. The method is using a threshold two-tuple, combining a polarimetric ENL estimator with CFAR to reveal ship region of interesting (ROI). The ROIs are then further investigated by polarization synthesis. An optimal VV/HH ratio was calculated for both ship and speckle, and a Polarization Orientation Angle (PAO) based analysis for microwave backscatter ship ROIs has further been carried out.
