The Canada Centre for Remote Sensing (CCRS) is considered an international leader in the development and use of synthetic aperture radar (SAR) sensors. From space, SAR can image the Earth’s surface through clouds and in total darkness. This makes it a tremendously useful sensor for monitoring Canada’s changing landmass and coastal zones.
CCRS scientists have worked with the Canadian Space Agency in the development of the RADARSAT 1, RADARSAT 2 and RADARSAT Constellation satellite missions. Their research has led to improved data quality and utility through enhanced sensor design, calibration and validation activities, and application development.
RADARSAT-1 Mosaic of Canada collected over a seven-day period in 1999
Using RADARSAT data, as well as SAR data from foreign sensors (e.g. TeraSAR-X, ALOS), new methods are being developed to measure and monitor:
- Surface water (incl. flooding) and wetlands
Polarimetric RADARSAT-2 for Monitoring Canadian Wetlands
Monitoring Open Fresh Water in Northern Environment, Using SAR imagery and FnFCE
- Freshwater lake and river ice
Mapping and Monitoring Lake Ice using SAR Satellites
River Ice Mapping and Monitoring using SAR Satellites
- Surface deformation and slope stability
InSAR Measurements of Terrain Stability in Canada's North
InSAR monitoring of permafrost activity, NWT, Canada
Past research has focused on:
- 3D Radargrammetric Modeling of RADARSAT-2 Ultra-Fine Mode: Preliminary Results of the Geometric Evaluation
Launched in June 2019, the RADARSAT Constellation Mission (RCM) provides daily coverage of Canada. Through their radar science, CCRS has contributed significantly to ensuring RADARSAT users inside and outside the Government of Canada are ready to use RCM data.
