The availability of polarization diversity on second generation SAR satellites will increase the information available for sea ice monitoring. In preparation for RADARSAT-2, MDA has been working closely with the Canadian Ice Service to analyze the potential and challenges of the use of dual-polarization and polarimetric data. These efforts include the analysis of airborne polarimetric SAR data of sea ice, the simulation of RADARSAT-2 products, as well as the analysis of a multi-temporal ENVISAT ASAR APH data set acquired in the Canadian Arctic. The emphasis of past work was to evaluate the utility of the increased information content for classification (ice vs. open water as well as different ice types) and visualization with respect to an operational environment.
Current efforts include the development of a pilot demonstrator. On the basis of research results, workflows and algorithms are being developed for a semi-operational environment. The final phase of the project includes a demonstration using RADARSAT-2 multi-polarization and polarimetric data.
In this paper, we will present a summary of past efforts, provide results and conclusions, and give an overview of planned work.
