Abstract

L'invention concerne un procédé d'extension de la plage de mesure d'un dispositif de mesure comprenant une antenne (D) permettant de déterminer une vitesse et/ou un trajet, notamment d'un véhicule ferroviaire (F) au-dessus du sol sur la base de l'effet Doppler. L'invention concerne également un dispositif de mesure pour la mise en oeuvre du procédé. L'invention vise à mesurer les vitesses même faibles et jusqu'à l'arrêt. A cet effet, on anime l'antenne (D) d'un mouvement oscillant et on détermine la vitesse et/ou le trajet en combinant un signal mesuré et un signal d'oscillation.
