Title (EN) MEASUREMENT ARRANGEMENT
(FR) AGENCEMENT DE MESURE
Abstract:
(EN) A measuring device for determining the thickness of a non-homogenous medium such as the thickness or a road structure. The device includes a radar transmitter Tx and two spaced receivers Rx1, Rx2. Information on the timing of the transmitted signal as well as the signals received by the two receivers is used to calculate the material thickness whilst eliminating signal drift.
(FR) Cette invention concerne un dispositif de mesure destiné à l'évaluation de l'épaisseur d'un milieu non homogène du type structure routière. Ledit dispositif comporte un émetteur radar (Tx) et deux récepteurs espacés (Rx1, Rx2). On utilise les informations relatives aux instants d'émission du signal et de réception des signaux par les deux récepteurs pour calculer l'épaisseur du matériau tout en éliminant la dérive du signal.
