Abstract

L’invention concerne un système de télémétrie (1) d’un véhicule automobile comprenant un premier module d’émission apte à émettre un premier faisceau lumineux (F1a) modulé par une première séquence modulante (Seqa) ; un deuxième module d’émission (2b) apte à émettre un deuxième faisceau lumineux (F1b) modulé par une deuxième séquence modulante (Seqb) ; un module de réception (3a, 3b) apte à recevoir un faisceau lumineux (F2) et à en extraire une séquence de données démodulée (Seq2) ; une unité de calcul (4) agencée pour générer des première et deuxième séquences de données modulantes (Seqa, Seqb) de type binaire pseudo-aléatoire et dont le pic de la fonction de corrélation (Fcorr) croisée est inférieur à une valeur seuil (Vs) et agencée pour estimer des valeurs d'une fonction de corrélation (Fcorr) entre ladite séquence de données démodulée (Seq2) et ladite première séquence de données modulante (Seqa).
