摘要
This is an update on RADARSAT-2 SAR image quality and calibration, showing the stability of key measures including radiometric accuracy, geolocation accuracy, resolution, noise levels, and precise beam pointing. Ongoing calibration adjustments for seasonal variations in phase differences between antenna wings in dual-receive-aperture modes are described. Future improvement goals are discussed.
