A proximity sensor having a generator providing a signal of which a small portion is used as a reference signal and the remaining portion is radiated out towards a target. The radiation reflected from the target is equalized and/or normalized relative to the reference signal. The signals are compared in terms of relative phase relationship. This relationship implies the distance of the target from an antenna. An example target may be a rail wheel. A certain part of the wheel is measured in terms of distance from the sensor. This distance may determine wheel wear. Such wear is gauged relative to a threshold signal or reference distance. Also, speed and direction of the rail wheel can be determined from the signal reflected back to the proximity sensor.

L'invention concerne un capteur de proximité doté d'un générateur qui émet un signal dont une petite partie est utilisée comme signal de référence et le reste rayonne vers une cible. Le rayonnement réfléchi par la cible est égalisé et/ou normalisé par rapport au signal de référence. Les signaux sont comparés en termes de relation de phase relative. Cette relation implique la distance de la cible à partir d'une antenne. Un exemple de cible peut être une roue de véhicule sur rail. Une certaine partie de la roue est mesurée en termes de distance à partir du capteur. Cette distance peut permettre de déterminer l'usure de la roue. Cette usure est calibrée par rapport à un signal seuil ou à une distance de référence. De même, on peut déterminer la vitesse et la direction de la roue de véhicule sur rail à partir du signal rétroréfléchi au capteur de proximité.
