             abstract = "In this study, preliminary results on the capability of 
                         Hybrid-Polarity (HP) Synthetic Aperture Radar (SAR) architectures 
                         to observe ice scenarios are presented. HP features, emulated from 
                         real fully-polarimetric L-band SAR data exploiting fundamentals of 
                         wave polarimetry concepts, are considered and tested over a large 
                         dataset consisting of 5 ALOS-PalSAR acquisitions gathered over the 
                         Svalbard Norwegian archipelago in the Arctic Ocean, and over the 
                         Terra Nova Bay in Antarctica. They represent extremely complex 
                         scenarios characterized by permanent glaciers, sea ice, 
                         snow-covered mountains, ice tongues, etc. Furthermore, the type of 
                         snow and ice covering Arctic and Antarctic lands and seas shows a 
                         strong daily and seasonal variability, making such environments 
                         very difficult to analyze. Their adverse atmospheric conditions 
                         make remote sensing a crucial tool to study such regions, which 
                         represent a key source of information about the global climate 
                         change. However, when dealing with SAR observations, the 
                         complexity of those environments in terms of scattering mechanisms 
                         makes this task not straightforward. In this study, some 
                         meaningful experiments demonstrate the capability of HP 
                         architectures to provide valuable information on Arctic and 
                         Antarctic regions. The polarimetric set of HP features, including 
                         wave entropy, degree of polarization, complex correlation 
                         coefficient and circular polarization ratio has shown to provide 
                         interesting signatures of the different scenarios within ice 
                         areas, when combined together. However, to avoid wrong 
                         interpretations of the polarimetric results caused by terrain 
                         azimuth slopes a pre-processing step constiting of compensate the 
                         polarization angle effects due to the terrain azimuth slopes is 
                         accomplished.",
