Abstract

La présente invention concerne un procédé de classification de mouvement d'une cible mobile au moyen d'un signal radar reçu en provenance de la cible. Le procédé comprend les étapes consistant à créer différents modèles spécifiques au mouvement à l'aide d'un modèle de Markov caché pour tous les mouvements souhaités à classer ; obtenir une base de données qui comprend les différents modèles de mouvement créés ; détecter une cible par un radar pulsé ; déterminer la cellule de portée de la cible détectée dans un intervalle de traitement cohérent ; stocker des signaux reçus, à chaque impulsion dans un intervalle de traitement cohérent, en provenance de la cible dans ladite cellule de portée ; trouver des vecteurs de caractéristique, à une certaine fréquence, à partir d'un signal continu obtenu en traitant les signaux stockés et en les ajoutant ensemble ; générer une série temporelle de vecteurs de caractéristique en disposant les vecteurs de caractéristique trouvés successivement ; comparer la série temporelle de vecteurs de caractéristique générée aux modèles de mouvement basés sur un modèle de Markov caché dans la base de données de façon à calculer sa probabilité pour chaque modèle de mouvement qui est présent dans la base de données ; sélectionner le mouvement déterminé par le modèle de mouvement ayant la probabilité calculée la plus élevée en tant que mouvement de la cible.
