A polarimetric and PolInSAR analysis has been conducted on the Nezer forest (Southern France) at L and P band on high resolution SAR data acquired with the ONERA RAMSES system in January 2004. The P and L band data was acquired simultaneously and several tracks with the same route were flown in order to allow multi-pass interferometry processing. We processed different couples characterised by different baselines. In the paper, we present the dataset and describe the PolInSAR inversion procedure specially adapted to P band data. The dataset was investigated for its potential for retrieval of forest parameters from SAR data using three different techniques: - Radiometric inversion from the cross-polarized term, - PolInSAR inversion based on the random-volume over ground model - An approach based on the anisotropy parameter. This paper concentrated on PolInSAR inversion whereas a sister paper in this conference describes the polarimetric and radiometric approaches.
