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 and image quality performance based on imagery of the Amazon rain forest, and of the RADARSAT-1 Precision Transponders. This paper briefly describes image quality results and recalibration work.
