Potential of RADARSAT-2 data for operational sea ice monitoring
Synthetic aperture radar (SAR) data from RADARSAT-1 are an important operational data source for several ice centres around the world. Whereas RADARSAT-1 is only capable of acquiring data at a single polarization, RADARSAT-2 will be capable of acquiring dual-polarization data in many wide-swath modes (most importantly ScanSAR) and fully polarimetric SAR data in a narrow 25-km swath mode. In thi...
متن کاملVisibility of Turbulent Ship Wakes in Dual- Polarized RADARSAT-2 Imagery
--The observations of ship wakes in RADARSAT-2 Synthetic Aperture Radar fine beam mode images are described. Wakes were observed in about 50 percent of cases where ship detection was accompanied by an Automatic Identification of Ships (AIS) report. These were mostly turbulent wakes. The goal of the research was to understand the physical mechanisms and the factors involved in the visibility of ...
متن کاملRADARSAT-2 Polarimetric SAR Data for Urban Land Cover Classification: A Multitemporal Dual-Orbit Approach
This research investigates multitemporal dual-orbit RADARSAT-2 polarimetric SAR data for urban land cover classification using an object-based support vector machine (SVM). Sixdate RADARSAT-2 high-resolution SAR data in both ascending and descending orbits were acquired in the rural-urban fringe of the Greater Toronto Area during the summer of 2008. The major landuse/land-cover classes include ...
متن کاملOperational Surface Water Detection and Monitoring Using Radarsat 2
Traditional on-site methods for mapping and monitoring surface water extent are prohibitively expensive at a national scale within Canada. Despite successful cost-sharing programs between the provinces and the federal government, an extensive number of water features within the country remain unmonitored. Particularly difficult to monitor are the potholes in the Canadian Prairie region, most of...
متن کاملPotential of RADARSAT-2 for Sea Ice Classification
Polarimetric data acquired by the CCRS CV-580 airborne SAR is used to assess the capability of RADARSAT-2 for operational sea ice classification. The information content of the polarimetric data is illustrated by showing how specific scattering mechanisms are portrayed by the entropy, anisotropy and α-angle features. Ice type classes are derived from the full pol data set using a complex Wishar...
