| Résumé | (disponible en anglais seulement)
A SAR with hybrid-polarity architecture (CL-pol) transmits circular polarization and receives two orthogonal mutually-coherent linear polarizations, which is
one manifestation of compact polarimetry. The resulting radar is relatively simple to implement, and has unique self-calibration features and low susceptibility to noise and cross-channel errors. It also enables maintaining larger swath coverage
than fully polarimetric SAR systems. A methodology was developed at CCRS for a comparison of fully polarimetric data with compact polarimetry data for applications important to the GoC, under the Understanding Canada from Space and the Groundwater
Mapping programs. This compact polarimetry mode configuration for a SAR satellite was evaluated for soil moisture estimation and wetland mapping applications. This paper will present the approach developed and provide some example analyses
techniques including results for wetland classification and soil moisture estimation. The implications of the results are also discussed with respect to future SAR missions such as the RADARSAT Constellation or India's RISAT. |
