Abstract
Une méthode et un système dimagerie tridimensionnelle par ouverture synthétique sont décrits. La méthode et le système utilisent la modulation spatiale sur les signaux de retour de louverture synthétique comme fonction de leur distribution dangles de retour pour tenir compte de la topographie locale et fournissent des capacités dimagerie tridimensionnelle. Selon certains modes de réalisation, la méthode peut comprendre une étape de génération de deux images bidimensionnelles modulées dans lespace par ouverture synthétique dune région cible, chacune ayant un profil de modulation spatiale différent, et une étape de fusion des deux images pour former une image tridimensionnelle par ouverture synthétique. Cette image peut être utilisée pour déterminer une carte délévation de la région cible.
