Abstract :
Calibration 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. SAR data of the Ottawa region containing passive and active point targets have been received monthly and analyzed beginning in June, 1992. Processing has been performed at the Canadian Data Processing Facility at the Gatineau Satellite Station (GSS). Over a 10 month period, the variability in the system calibration constant for ERS-1 of ±1.0 dB has been found. Variations in the power of the pulse replica of ±0.2 dB have been observed between June 6, 1992 and March 13, 1993
