AbstractThe Canadian RADARSAT Constellation Mission (RCM) will consist of three synthetic aperture radar (SAR) satellites to be launched in 2018. The Constellation 4-day revisit period will allow monitoring ground uplift and subsidence in Alberta's oil sands, where the steam assisted gravity drainage (SAGD) and the cyclical steam stimulation (CSS)-enhanced oil recovery operations are employed for extracting viscous bitumen. Fast ground deformation occurring over a small area can only be captured by high-resolution, low-noise SAR. A large deformation gradient limits applicability of coarser resolution SAR, making accurate phase unwrapping impossible, especially in regions susceptible to significant temporal decorrelation. In this study we analyzed the suitability of RCM for monitoring ground deformation in Alberta's oil sands using interferometric SAR (InSAR) methodology. RCM SAR sensor differs from RADARSAT-2 in resolution, coverage, polarimetric configuration options, and radiometry. Various RCM-simulated products were created, for which InSAR analysis was performed and the average coherence was computed as a function of the spatial resolution and the noise floor. We determined that noise floor moderately affects InSAR coherence; the main limitation is imposed by coarse resolution of RCM beams. The very high resolution and high resolution RCM beams are most suitable for monitoring ground deformation in Alberta's oil sands.
