Abstract

Procédé de gestion d'une installation d'émission-réception d'ultrasons (20) consistant à : - émettre un premier signal représentant un premier mode code par un premier capteur à ultrasons (1) d'un premier groupe (G 12) dans un premier cycle de mesure, - émettre un second signal à l'aide d'un second capteur à ultrasons (2) du premier groupe (G 12), - recevoir l'écho du premier signal et du second signal par un troisième capteur à ultrasons (1, 2), et - distinguer entre la partie de l'écho provenant du premier signal et celle du second signal en décodant le mot de code.Method for managing an ultrasound transmission-reception installation (20) consisting in: - transmitting a first signal representing a first code mode by a first ultrasonic sensor (1) of a first group (G 12) in a first measurement cycle, - send a second signal using a second ultrasonic sensor (2) of the first group (G 12), - receive the echo of the first signal and the second signal by a third sensor at ultrasound (1, 2), and - distinguish between the part of the echo coming from the first signal and that of the second signal by decoding the code word.
