AbstractCalibration studies are being conducted at the Canada Centre for Remote Sensing (CCRS) in preparation for RADARSAT using data obtained from the ERS-1 SAR system. These studies are providing an understanding of the ERS-1 SAR system performance, giving input to the evaluation of calibration methodology (including the use of point targets and system information) and hardware and software development to be used for calibration of RADARSAT products. Over a 7 month period, the variability in the system calibration constant for ERS-1 of +- 0.45 dB has been found with the exception of data from October 24, 1992 where a significant radiometric anomaly (of approximately 3.0 dB) has been observed. Variations in the power of the pulse replica of ± 0.19 dB have been observed between June 6, 1992 and January 2, 1993. (From Author)
