Abstract

Cette invention concerne un procédé et un dispositif qui se rapportent au domaine des techniques radio, plus précisément à celui de la radiolocalisation et de la radionavigation, et qui peuvent être utilisés dans des techniques de mesures radio. Ce procédé de mesure d'une distance consiste à modifier plusieurs fois la fréquence du signal émis de manière à établir des valeurs données de différence de phases des signaux émis et reçu. On mesure ensuite chaque valeur de fréquence du signal, on calcule la caractéristique de réponse en phase, et l'on sépare de cette dernière les composantes linéaire et périodique dont les paramètres permettent de déterminer les distances parcourues par le signal le long d'une trajectoire principale ou d'autres trajectoires. Ce dispositif de mesure d'une distance (Fig. 4) comprend les éléments suivants: un générateur (1) dont la fréquence est commandée en tension et dont le signal est émis par la sortie (3); un système de comparaison de phases (5) connecté à la sortie du générateur et à l'entrée d'un dispositif (4) qui forment tous deux un système d'ajustement automatique de la fréquence du générateur (1); une unité de mesure (7) de la fréquence du générateur; un système de calcul (8); et enfin, un système de commande programmé de type unité de commande (10). L'une des sorties du détecteur de phase (5) peut être connectée à un inverseur de phase (11) commandé par l'unité de commande, tandis que l'entrée et la sortie du dispositif peuvent être connectées à des clés (12, 13) assurant un mode d'impulsions quasi ininterrompu.
