Flattening Gamma: Radiometric Terrain Correction for SAR Imagery

  title={Flattening Gamma: Radiometric Terrain Correction for SAR Imagery},
  author={David Small},
  journal={IEEE Transactions on Geoscience and Remote Sensing},
Enabling intercomparison of synthetic aperture radar (SAR) imagery acquired from different sensors or acquisition modes requires accurate modeling of not only the geometry of each scene, but also of systematic influences on the radiometry of individual scenes. Terrain variations affect not only the position of a given point on the Earth's surface but also the brightness of the radar return as expressed in radar geometry. Without treatment, the hill-slope modulations of the radiometry threaten… CONTINUE READING
