Recent advances in Polarimetric SAR Interferometry for forest parameter estimation

Polarimetric SAR Interferometry (Pol-InSAR) is a radar remote sensing technique that, based on the coherent combination of SAR interferometry and radar polarimetry, provides sensitivity to the vertical distribution of different scattering processes and makes the inversion of forest structure parameters possible. In this paper we present the main scientific results achieved in actual airborne campaigns, discuss the potential and limitations of the different inversion scenarios (based on different frequencies, temporal and spatial baselines) and draw the conclusions.
