AfriSAR is an ESA-funded airborne P-band SAR campaign over the African tropical forests of Gabon that was carried out by ONERA (July 2015) and DLR (February 2016) in support of
the development of the geophysical algorithms of the future BIOMASS mission. In addition, DLR will complement the P-band data set with L-band over the same sites. Both data sets will be
constituted by properly designed multibaseline fully polarimetric acquisitions allowing the inversion of key forest vertical structure-based parameters, like e.g. forest height and high
resolution reflectivity profiles. A first processing result of the acquired data and parameter inversion is shown in this paper at both frequencies.
