RADARSAT-1 deformation time-series generation by using the SBAS-DInSAR algorithm

We have extended the deformation time-series generation capability of the small baseline subset (SBAS) DInSAR algorithm to the SAR data collected by the RADARSAT-1 sensor. The selected SBAS algorithm relies on conventional multi-look interferograms characterized by small temporal and spatial baseline values. We present in this work the first results achieved by exploiting the implemented RADARSAT-1 SBAS-DInSAR processing chain. The investigated test site is the area of New Orleans and its surroundings, for which a RADARSAT-1 archive of 27 acquisitions, spanning the time interval between December 2004 and March 2007, has been processed. The presented results demonstrate the effectiveness of the RADARSAT-1 SBAS-DInSAR processing chain.
