The BACCHUS-DOC Radar and Optical Campaign was an area mapping project of
vineyards near Frascati (Italy). ESA required high resolution geo-referenced airborne SAR data of different wavelength and polarisation (preferably polarimetric).
The 2004 Envisat and ERS Symposium was held in Salzburg - Austria from 6 to 10 September 2004. The 2004 Envisat and ERS Symposium provided a forum for investigators to present results of ongoing research project activities and assess the development of applications and services.
This paper describes the status of the ERS-1 SAR radiometric calibration with updated measurements on the radiometric stability. The calibration measurements arc performed using the transponders deployed by ESA/ESTEC in Flevoland, The Netherlands. The calibration measurements are the result of a joint effort between the ESA Processing and Archiving Facilities (PAF) and the ERS Central Facility at ESA/ESRIN.
