Synthetic aperture radar analysis of floating ice at Terra Nova Bay—an application to ice eddy parameter extraction
In the framework of a study of ice formation in Antarctica, synthetic aperture radar (SAR) image acquisitions were planned over Terra Nova Bay (TNB). Thanks to the European Space Agency (ESA) Third Party Mission program, Cosmo-SkyMed and Radarsat-2 images over TNB were obtained for the period of Feb...
