An initial assessment of RADARSAT-2 and TerraSAR-X pol-InSAR acquisitions over Ottawa

Inhalt:
In the spring of 2010, a series of TerraSAR-X and RADARSAT-2 fully polarimetric and interferometric synthetic aperture radar (SAR) data sets were acquired over a mixed urban and parkland portion of the city of Ottawa. One set of polarimetric acquisitions were imaged within 7 minutes of each other from a similar geometry. Interferometric SAR (InSAR) pairs from each sensor are also well-matched temporally. This afforded a unique occasion for a polarimetric and interferometric analysis of different land cover classes at the two different sensor wavelengths. In this paper, five land cover classes were selected for detailed analysis and discussion. They include urban, forest, wetland, agriculture and grass.
