Current approach is to find tambov constant based on experiments with reference data (PM #3 Andrea's comments)

Clues could be found in pg 22 and on in ER-IS-EPO-GS-0201

These two documents describe calibration:

  • ENVISAT - ASAR_products_absolute_calibration_v1.5.pdf
  • s3://sar-focusing/docs/ERS-1-SAR-Radiometric-Calibration.pdf
