AbstractThis paper summarizes the calibration monitoring activities of the Canadian Space Agency (CSA) executed under the RADARSAT Program. The performance history of the RADARSAT-1 SAR since its commissioning in 1996 is reviewed, along with the calibration systems and methodologies used, in the context of the mission's thirteen-year calibration history. Independent image quality measurements for the privately-owned RADARSAT-2, launched in 2008, are also presented. It is shown that the calibration parameters of the RADARSAT-1 SAR have consistently been maintained within the mission's design goals and specifications, mostly thanks to payload stability and timely recalibrations performed using the calibration ground equipment. For RADARSAT-2, CSA's measurements report outstanding image quality levels.
