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 ...

Assessing the Benefits of Simulated RADARSAT Constellation Mission Polarimetry Images for Structural Mapping of an Impact Crater in the Canadian Shield

Canadian Journal of Remote Sensing, 2018
Traditional polarization architectures transmit and receive linear polarizations (LL). Canada’s RADARSAT Constellation Mission (RCM) will be equipped with a hybrid architecture that will transmit a circular polarization and receive linear polarizations ...

Arctic Sea Ice Topography Information From RADARSAT Constellation Mission (RCM) Synthetic Aperture Radar (SAR) Backscatter

Geophysical Research Letters
Sea ice topography information can be obtained from altimetry but these data are spatially and temporally limited compared to recent synthetic aperture radar (SAR) missions such as the RADARSAT Constellation Mission (RCM).

Assessment of the High Resolution SAR Mode of the RADARSAT Constellation Mission for First Year Ice and Multiyear Ice Characterization

Remote Sensing, 2018
Simulated compact polarimetry from the RADARSAT Constellation Mission (RCM) is evaluated for sea ice classification. Compared to previous studies that evaluated the potential of RCM for sea ice classification, this study focuses on the High Resolution ...

Arctic ice-wedge landscape mapping by CNN using a fusion of Radarsat constellation Mission and ArcticDEM

Remote Sensing of Environment
In Canada\u27s Arctic tundra region, permafrost is continuous, and the landscape is rich in patterned features. Polygonal terrain, which includes both high- and low-centered features and their wet trenches below, is considered to be high-latitude ...

Surface Soil Moisture Estimation from Time Series of RADARSAT Constellation Mission Compact Polarimetric Data for the Identification of Water-Saturated Areas

Remote Sensing
Soil moisture is one of the main factors affecting microwave radar backscatter from the ground. While there are other factors that affect backscatter levels (for instance, surface roughness, vegetation, and incident angle), relative variations in soil ...

Detection of Actionable Oil using RADARSAT-2 and Simulated RADARSAT Constellation Mission Data [PDF]

International Oil Spill Conference Proceedings, 2021
Abstract 688970 For oil spill response, one of the key parameters is detection of actionable oil. Actionable oil (AO), which tends to be thick, emulsified oil, refers to oil that can be cleaned-up versus non-actionable oil (sheen) which cannot be readily cleaned-up. Previous studies by MDA of a controlled oil spills in the North Sea have
