Abstract: International audience; Speckle characteristics was analyzed by computing the ENL (Equivalent Number of Looks) for sub images of 30 by 30 pixels from four RADARSAT-2 dual polarization products, two single look complex (SLC) products acquired in wide swath single beam mode with dual polarization of HH+HV and two ScanSAR Wide (SCW) products acquired in ScanSAR Wide beam mode with dual polarization of HH+HV, which lie in the sea area around Iberian Peninsula. The speckle analysis indicates that ENL value combined with the intensity value of the SA...
