Performances d'algorithmes de focalisation en traitement SAR spatial très haute résolution

Future spatial synthetic aperture radar image applications will need metric or submetric resolution that are called very high resolution in this paper. Very high resolution processing in spatial implies news signal processing and a new instrument and some of the hypothesis used today, often coming from airborne case, are no more available. The aim of this paper is to describe some processing used in a very high resolution spatial radar chain and to illustrate the performances and robustness of this chain.
