ESTABLISHING CROP PRODUCTIVITY USING RADARSAT-2 [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012 Crop productivity is influenced by a number of management and environmental conditions, and variations in crop growth can occur in-season due to, for example, unfavourable meteorological conditions.

Operational Surface Water Detection and Monitoring Using Radarsat 2
Remote Sensing, 2016 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 ...

ScanSAR interferometry for RADARSAT-2 and RADARSAT-3
Canadian Journal of Remote Sensing, 2004 Among the interferometric modes and applications of RADARSAT-2 and RADARSAT-3, ScanSAR interferometry is interesting because of its wide swath imaging capabilities. It allows efficient mapping of the earth's surface topography and its changes, and poses several interesting requirements on instrumentation, data acquisition, and processing.

Mineral Oil Slicks Identification Using Dual Co-polarized Radarsat-2 and TerraSAR-X SAR Imagery
Remote Sensing, 2020 This study is devoted to a generalization of C-band Radarsat-2 and X-band TerraSAR-X synthetic aperture radar (SAR) data in the form of a diagram serving to easily identify mineral oil slicks (crude oil and emulsions) and separate them from the other oil

Spring melt pond fraction in the Canadian Arctic Archipelago predicted from RADARSAT-2 [PDF]
The Cryosphere, 2020 Melt ponds form on the surface of Arctic sea ice during spring, influencing how much solar radiation is absorbed into the sea ice–ocean system, which in turn impacts the ablation of sea ice during the melt season. Accordingly, melt pond fraction (fp) has

Combining Machine Learning and Compact Polarimetry for Estimating Soil Moisture from C-Band SAR Data
Remote Sensing, 2019 This research aimed at exploiting the joint use of machine learning and polarimetry for improving the retrieval of surface soil moisture content (SMC) from synthetic aperture radar (SAR) acquisitions at C-band. The study was conducted on two agricultural

A New Method to Create a Virtual Third Antenna from a Two-Channel SAR-GMTI System [PDF]
, 2007 Two-channel SAR-GMTI systems are suboptimal for moving target motion parameter estimation. Indeed, the ATI phase estimate of the across-track velocity component for a moving target is biased to lower values depending on the target signal to clutter ...
