Abstract :
RADARSAT-1, the first Canadian SAR remote sensing satellite has successfully completed its design lifetime of five and a quarter years. It is in extended mission operation meeting customer demand. The Image Quality Control program is kept fully operational. Measured results indicate image quality performance is better than system specification and maintained. This paper briefly describes image quality results and recalibration work.
