Abstract

Les modes de réalisation de l’invention fournissent un procédé de prédiction de l’état d’une cible mobile (101) mis en œuvre dans un système de surveillance (100) comprenant un viseur optronique (104) et un dispositif de tir de projectiles (105) configuré pour tirer un ou plusieurs projectiles selon une séquence de tir donnée. Le procédé de prédiction comprend les étapes consistant à : - recevoir une pluralité de mesures brutes ; - sélectionner parmi les mesures brutes une ou plusieurs mesures brutes valides en fonction de la séquence de tir et en fonction d’un ou de plusieurs paramètres d’erreur ; - estimer à partir des mesures valides et à partir de la séquence de tir une cinématique courante de la cible mobile (101) et un modèle dynamique de mouvement vraisemblable ; - déterminer un point de rendez-vous spatio-temporel ; - calculer une pluralité de paramètres de tir permettant d’intercepter la cible mobile (101).
