(EN) METHOD AND DEVICE FOR MEASURING A DISTANCE

Abstract
(EN)
The present invention pertains to the field of radio techniques, more precisely to that of radio location and radio navigation, and essentially relates to a method and a device that can be used in radio measuring techniques. This method for measuring a distance involves modifying several times the frequency of the outputted signal in order to establish given values of phase difference for the outputted and received signals. The method further involves measuring each value of signal frequency, calculating the phase response characteristic and separating from the latter the linear and periodical components whose parameters are used for determining the distances covered by the signal along a main trajectory or other trajectories. The distance measuring device of the present invention includes the following members: a generator (1) having a voltage-controlled frequency and whose signal is emitted through the output (3); a phase comparison system (5) connected to the output of the generator and to the input of a device (4) that define together an automatic adjustment system for the frequency of the generator (1); a unit (7) for measuring the generator frequency; a computing system (8); and a programmed control system such as a controller (10). One output of the phase detector (5) may be connected to a phase shifting unit (11) controlled by the controller, while the input and the output of the device may be connected to keys (12, 13) ensuring a quasi-uninterrupted pulse mode.

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.
