Abstract :
RADARSAT-1, the first Canadian SAR remote sensing satellite, was launched on November 4, 1995. After commissioning, it was put into routine operations on April 1, 1996. In September 1997, RADARSAT-1 underwent a major configuration change to accommodate the Antarctic Mapping Mission (AMM - a joint mission by Canada and USA aimed at completing high-resolution mapping of Antarctica) for a period of about five weeks. Significant effort continues to be expended in the provision of high quality products to users generated by the Canadian Data Processing Facility (CDPF). The image quality measurement results indicate that the RADARSAT-1 system is meeting and exceeding its performance specification and that image quality is maintained. This paper will describe the overall process of data acquisition, data analysis and re calibration for image quality maintenance
