This paper describes the role of the Canadian Space Agency (CSA) in calibration monitoring activities of the SAR on-board the two RADARSAT satellites currently in orbit. First, the performance of the RADARSAT-1 SAR since commissioning in 1996 is reviewed, along with the calibration systems and methodologies in the context of the mission's eleven-year calibration history. Calibration monitoring activities...
This paper examines the calibration performance of the RADARSAT-1 products since spacecraft commissioning in 1996, and briefly reassesses the calibration ground systems and methodologies in the light of the mission's twelve-year calibration experience and data record. Choices made in the design, deployment and implementation of the RADARSAT-1 calibration plan are retrospectively explored in the context...
This paper describes the image quality control activities performed at the Canadian Space Agency on RADARSAT-1, and presents the preparations for calibration support activities for RADARSAT-2. Radiometric calibration and image quality performance of the RADARSAT-1 SAR is monitored routinely since its commissioning in 1996, based on imagery of the Amazon and of Precision Transponders. Antenna elevation...
Since its launch on November 4, 1995 and the start of the routine operation on April 1, 1996, RADARSAT-1, the first Canadian Synthetic Aperture Radar (SAR) remote sensing satellite, has provided calibrated data to worldwide users for their intended applications. From the early qualification stages of the mission, both single beams and ScanSAR operating modes are monitored routinely for radiometric...
