AbstractThis paper reviews image quality and radiometric calibration aspects of the first two years of operation of RADARSAT. This includes the calibration of almost all beams (a total of more than 25 beams when considering shifted positions of each of the Fine beams), and the stability and calibration accuracies achieved during the mission to date. The measurements show that the SAR performance is better than the specifications. In September 1997, RADARSAT underwent a major configuration change to accommodate the Antarctic Mapping Mission for a period of about five weeks. To achieve this, the spacecraft was rotated to allow imaging from a left-looking geometry. The image quality and calibration results for the left-looking mode are also discussed.
