For more than one decade, the scientific developments carried out with spaceborne synthetic aperture radar (SAR) have demonstrated that SAR is a reliable remote sensing technique to analyze wave fields on the open ocean. In their so-called image mode, these SAR systems, such the Advanced SAR (ASAR) ENVISAT, are able to scan ocean areas of 100 x 100 km 2 and more with spatial resolutions about 20 x 20 m 2 . Those SAR images are able to provide information about the spatial variability of 2D wave fields. This work investigates the potential of ENVISAT ASAR capability to scan the ocean surface with dual polarizations. The relevance of these investigations for different practical applications concerning the analysis of ocean waves is discussed.
