Abstract	La surveillance du trafic maritime necessite de disposer de systemes efficaces permettant de detecter et de suivre des cibles diverses en continu jusqu'aux limites de la Zone Economique Exclusive (ZEE - 200 Milles Marins). Les radars Hautes-Frequences a ondes de surface (HFSW) sont de bons candidats pour repondre a ces exigences. Cependant les images obtenues en sortie de ces systemes sont fortements perturbuees pour des applications de detection. Dans cette contribution nous proposons d'utiliser d'une part la transformee en curvelets pour supprimer certains aspects limitants dans l'image. D'autre part, de baser notre methode de detection sur les ondelettes continues (appliquees a l'image pre-traitee par les curvelets).
