Polarimetric Approaches for Persistent Scatterers Interferometry [PDF]

open access: yes, 2014
In previous works, a general framework to exploit polarimetric diversity to optimize the results of persistent scatterers interferometry (PSI) was presented, but tested only with dual-pol data.

Scattering‐Based Model of the SAR Signatures of Complex Targets for Classification Applications

open access: yesInternational Journal of Navigation and Observation, Volume 2008, Issue 1, 2008., 2008
The modeling of complex target response in SAR imagery is the main subject of this paper. The analysis of a large database of SAR images with polarimetric and interferometric capabilities is used to accurately establish how the different structural parts of targets interact with the incident signal.

Regression-Based Retrieval of Boreal Forest Biomass in Sloping Terrain using P-band SAR Backscatter Intensity Data [PDF]

open access: yes, 2013
A new biomass retrieval model for boreal forest using polarimetric P-band synthetic aperture radar (SAR) backscatter is presented. The model is based on two main SAR quantities: the HV backscatter and the HH/VV backscatter ratio.
