Interferometry for DEM and Terrain Displacement: Effects of Inhomogeneous Propagation

La mesure d'un modele numerique de terrain (MNT) et les mouvements actuels de la surface terrestre sont des applications principales de l'interferometrie radar a synthese d'ouverture satellitaire multipasse. Dans cet article, l'effet inhomogene de l'atmosphere sur la mesure de MNT pour l'Arctique et la mesure des mouvements actuels de la surface terrestre sont examines en utilisant des donnees des paires Tandem ERS-1/2 et RADARSAT. Deux paires de donnees RADARSAT ayant des ecarts orbitals larges qui optimisent la precision du MNT sont choisies. Les precisions et limitations generales pour les deux applications sont etablies.
