SAR tomography is a coherent imaging technique from which may be derived 3-D maps of the electromagnetic (EM) reflectivity of complex environnements, and which revealed particularly well adapted to forest characterization (to estimate height, density, underlying ground topography, biomass). It will be implemented for the first time in a spaceborne radar context, in the frame of ESA's Earth Explorer mission BIOMASS, to be launched in 2020. In particular, studies conducted at CESBIO showed that robust biomass estimators could be derived using P band data, over tropical forests in French Guyana. An analysis jointly led by IETR, IRSTEA and CNES further refined this approach and established an analytical realtionship using a simplified structural model.
