Abstract

RADARSAT-1 was launched in November, 1995 with the first image acquired on November 28 of that year. After commissioning, it was put into routine operation on April 1, 1996. Significant effort has been expended in the provision of radiometrically and geometrically calibrated products to users by the Canadian Data Processing Facility (CDPF). Particular emphasis has been on the determination of the antenna gain patterns and on image quality as measured using images of the Amazon rainforest and of the RADARSAT Precision Transponders (RPTs). This paper will review stability in image quality parameters and calibration accuracies as achieved to date, and present required parameter updates
