Abstract

L'invention appartient au domaine des équipements radio et notamment à la localisation radio. Elle peut s'utiliser pour mesurer à distance les caractéristiques de matériaux et d'objets ayant une forme complexe. L'invention permet d'améliorer la précision et l'authenticité de l'image radio détaillée de l'objet. Le procédé de l'invention consiste à mesurer l'intensité des signaux réfléchis à partir d'un site de travail à des angles déterminés, l'objet étant ensuite disposé sur le site de travail, à mesurer l'intensité finale des signaux réfléchis et à former une image radio de l'objet. Les mesures préliminaire et finale de l'intensité des signaux réfléchis sont en outre effectuées avec un rattachement aux éléments de résolution sur la portée. Au moyen d'une localisation discrète pas-à-pas on forme sur l'objet une tache dont le diamètre est inférieur à 0,6 m dans un plan perpendiculaire à l'axe d'irradiation, et avec une résolution sur la portée inférieure à 0,25 m. Pendant la formation de l'image radio on augmente de 180° la phase de l'intensité préalablement mesurée des signaux réfléchis et on effectue la sommation des mesures préliminaire et finale de l'intensité des signaux réfléchis en tenant compte de la phase. Le dispositif de mise en oeuvre du procédé de l'invention comprend un générateur UHF, un mélangeur, un amplificateur, une antenne d'émission / réception, un pointeur laser, une première et une deuxième caméras vidéo, un contrôleur vidéo, un modulateur de fréquence, un circulateur, un convertisseur analogique / numérique, un synchroniseur, un processeur, une unité de mémoire, une unité de traitement, un inverseur de phase et un tableau de commande.
