This paper focuses on the analysis of certain hypotheses considered in quantitative remote sensing of forest areas by means of Polarimetric SAR Interferometry (PolInSAR). When addressing the quantitative estimation of forest parameters in PolInSAR, the estimation is usually based on the inversion of the Random Volume over Ground (RVoG) coherent scattering model. We present an study of the validity of this assumption, based on the analysis of the measured data and the coherence region resulting from the variation of the interferometric coherence as a function of polarization.
