Title

(EN) SYSTEM AND METHOD FOR SAR-BASED 3D DEFORMATION MONITORING

(FR) SYSTÈME ET PROCÉDÉ DE SURVEILLANCE DE DÉFORMATION TRIDIMENSIONNELLE BASÉE SUR UN RSO

Abstract

(EN) A system and method for synthetic aperture radar (SAR) based three-dimensional (3D) deformation measurement is provided herein. The synthetic aperture radar (SAR) system includes a SAR computer system for three dimensional (3D) deformation monitoring having a 3D acquisition planner module that receives any one or more of multi-sensor characteristic data, target requirements data, and ancillary datasets, to generate an observation plan, a data acquisition module that transmits the observation plan to trigger the acquisition of SAR data from at least one SAR satellite, and an integration processing module that computes 3D surface displacement measurements from the SAR data to measure 3D deformation.

(FR) L'invention concerne un système et un procédé de mesure de déformation tridimensionnelle (3D) basée sur un radar à synthèse d'ouverture (RSO). Le système radar à synthèse d'ouverture (RSO) comprend un système informatique RSO pour une surveillance de la déformation tridimensionnelle (3D), avec : un module de planificateur d'acquisition 3D qui reçoit une ou plusieurs données caractéristiques multicapteur ; des données d'exigences cibles et des ensembles de données auxiliaires, pour générer un plan d'observation ; un module d'acquisition de données qui transmet le plan d'observation pour déclencher l'acquisition de données RSO à partir d'au moins un satellite RSO ; et un module de traitement d'intégration qui calcule des mesures de déplacement de surface en 3D à partir des données RSO pour mesurer une déformation tridimensionnelle.
