The Sentinel-1 constellation provides high resolution radiometrically calibrated SAR images with 6 days revisit and global coverage. The radiometric calibration was established during the Commissioning Phase exploiting transponders and natural targets. The paper describes the elevation antenna pattern verification based on the S-1 Antenna Model and the necessary refinements performed to achieve the requested radiometric accuracy.

Abstract
The Sentinel-1 constellation provides high resolution radiometrically calibrated SAR images with 6 days revisit and global coverage. The radiometric calibration was established during the Commissioning Phase exploiting transponders and natural targets. The paper describes the elevation antenna pattern verification based on the S-1 Antenna Model and the necessary refinements performed to achieve the requested radiometric accuracy.File in questo prodotto:
