The DEW Line Clean-Up proof-of-concept project was conducted to determine if space-based Synthetic Aperture Radar (SAR) data from the Canadian satellite RADARSAT-2 can be used for landfill monitoring at the DEW Line sites. Interferometric stacks (time series consisting of interleaved 24-day cycles) of RADARSAT-2 Spotlight mode images are being acquired over four of the former DEW Line sites. Results...
The Canadian Department of National Defence (DND) is cleaning up and remediating environmental hazards at former Distant Early Warning (DEW) Line sites located across the Canadian Arctic. The DEW Line Clean-Up proof of concept project is underway, to determine if space-based Synthetic Aperture Radar (SAR) data can be used for landfill monitoring at these DEW Line sites. Interferometric time series...
The detectability of crashed aircraft in RADARSAT-2 Ultra-Fine mode imagery of the Canadian North using automatic target detection algorithms has been examined. Optimization of algorithm parameters has been shown to decrease the number of false targets (those not of interest) which are detected. The use of multiple images can provide refinement in determination of potential target locations to Search...
Pressurized water reactors circulate high-temperature water that slowly corrodes Inconel and stainless steel system surfaces, and the nickel/iron based corrosion products deposit in regions of the fuel where sub-cooled nucleate boiling occurs. The deposited corrosion products, called ‘crud’, can have an adverse impact on fuel performance. Boron can concentrate within the crud in the boiling regions...
A reflectance-based vicarious calibration (RBVC) method has been used to correct the radiometric coefficients for hyperspectral data obtained with the Probe 1 sensor over the Raglan region of northern Quebec, and to perform a radiance renormalisation for compact airborne spectrographic imager (casi) data obtained over Goose Bay, Labrador. It relies on the simultaneous acquisition of ground-based reflectance...
