RADARSAT-1 Image Quality Excellence in the Extended Mission

Abstract

RADARSAT-1, the first Canadian SAR remote sensing satellite, continues to provide calibrated data to worldwide users since the start of its routine operation on April 1, 1996, more than 9 years after its launch on November 4, 1995. Both single beams and ScanSAR imagery are still monitored routinely for radiometric calibration performance based on images of the Amazon Rainforest, and for image quality performance using imagery of the RADARSAT-1 Precision Transponders. This paper briefly describes image quality results and recalibration work.
