Abstract
The paper discusses methods for radiometric calibration of repeat-pass interferometric SAR stacks based on Persistent Scatterers. Coherent and non-coherent approaches for the estimation of the radiometric gain are compared. Furthermore, an estimator of the beam pointing in elevation in proposed. Evaluation of performances is carried out basing on both simulated and COSMO-SKYMED data.
