ENVISAT RA-2 S-BAND RANGE CALIBRATION VERSUS KU-BAND RANGE, OVER THE SALAR DE UYUNI

摘要

It has been demonstrated that for the proper exploitation for the S-Band data, a calibration is required. Pildo Labs and UCL are presenting here a cross-calibration of the S-band range against the Kuband range, performed by comparing the S-band echoes against the Ku-band echoes over the salar Uyuni. This target has been chosen because of the very special nature of its return echo. A retracker suitable for the Uyuni echoes has also been developed.
