Nos études ont pour but la détection de cibles enfouies dans un environnement complexe pour des applications radar. Ce papier traite de nouveaux processeurs RSO (radar à synthèse d'ouverture) polarimétriques basés sur des détecteurs à sous-espace. Ces algorithmes utilisent des modèles de cibles incluant les propriétés physiques et polarimétriques de leur diffusion qui ne sont pas exploitées par le modèle de point isotrope généralement appliqué. Ces processeurs sont implementés en générant des sous-espaces qui contiennent les réponses d'intérêt de la cible. Nous présentons comme application la détection de cibles sous couvert forestier. Les résultats obtenus à la fois sur des données simulées de cibles réalistes et sur des données réelles montrent l'intérêt de ces nouveaux processeurs.
Our studies aim at detecting targets embedded in a complex environment for radar applications. This article deals with new polarimetric SAR (synthetic aperture radar) processors based on subspace detectors. These algorithms use models of targets including physical and polarimetric properties of their scattering on the contrary to the isotropic point model that is commonly used. These processors are implemented by computing the corresponding subspaces that contain the relevant responses of the target. We choose for application the detection of targets under forest foliage. The obtained results both on simulated data of realistic targets and real data show the interest of these new processors.
