Abstract

Système de mesure de parcours pour véhicules sur rails, comprenant un radar à effet Doppler permet de déduire par intégration le trajet parcouru. L'invention prévoit l'emploi d'au moins une antenne très directionnelle A1 inclinée par rapport à la direction du déplacement et destinée à capter les signaux réfléchis par la voie, et de jalons répondeurs espacés le long du parcours qui lors de leur franchissement déclenchent un signal convenu dans le dispositif de mesure de parcours, permettant ainsi de corriger l'évaluation obtenue par intégration de la fréquence Doppler. Application notamment en exploitation ferroviaire.Course measurement system for vehicles on rails, comprising a Doppler effect radar, enables the journey traveled to be deduced by integration. The invention provides for the use of at least one highly directional antenna A1 inclined with respect to the direction of movement and intended to pick up the signals reflected by the track, and responder markers spaced along the path which, when they are crossed, trigger a signal agreed in the course measuring device, thus making it possible to correct the evaluation obtained by integration of the Doppler frequency. Application in particular in railway operation.
