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.",
