Apport de la Polarimétrie à l'interférometrie radar pour l'estimation de hauteurs de cibles et de paramètres de forêt

Abstract : A recent development of radar polarimetry consists in its association with interferometry. Polarimetric analysis makes it possible to consider different scattering mechanisms within a given resolution cell, whereas interferometric techniques allow for a topographical characterization of the scattering contributions. Their combined application yields notable results for improving digital elevation models (DEM) or for forest parameters estimation thanks to coherent scattering models. The potential of several theoretical developments is tested using indoor measurements and real SAR data provided by the airborne system RAMSES in ONERA at P-, L- and X-band.
