Abstract

Le procédé comporte au moins : - un premier traitement radar (21) de localisation et d'estimation de trajectoire de ladite cible (1) à partir de mesures de distances radiales, de fréquence Doppler et d'angle d'azimut et d'élévation de ladite cible (1) issues d'un signal radar émis vers ladite cible (1) ; - un deuxième traitement radar (21) de localisation et de trajectoire de ladite cible (1) selon un axe vertical, par application du principe de l'antenne synthétique inverse ; l'écart entre ladite trajectoire donnée et la trajectoire estimée par ledit premier traitement projetée sur un plan horizontal et l'écart entre ladite trajectoire donnée et la trajectoire estimée par le deuxième traitement selon ledit axe vertical étant utilisés pour commander la direction de déplacement de ladite cible (1).
