Abstract

L'invention concerne un procédé de traitement d'un ensemble de données d'images radar SAR, comprenant une pluralité de trames de données d'images SAR pour chacune d'une pluralité de géométries d'images. Le procédé consiste, pour chaque géométrie d'image, à appliquer une détection de changements aux trames de données d'images SAR correspondant à ladite géométrie d'image pour produire une pluralité de produits de changements ; à sélectionner une pluralité desdites trames acquises en tant que trames de référence, à raison d'une par géométrie d'image ; à appliquer un traitement SAR multivisée aux trames de référence pour produire un produit SAR multivisée, ledit traitement comprenant au moins la mesure d'une propriété des données contenues dans les trames de référence et l'application aux données d'une transformation déterminée par la propriété mesurée ; et à appliquer aux produits de changements la même transformation que celle du traitement SAR multivisée, pour produire un produit de changement multivisée.
