Abstract

L'invention concerne un procédé pour caractériser un trajet de signal, ce procédé consistant à (i) générer (102) un signal de référence à spectre étalé; (ii) coupler (104) ce signal de référence à spectre étalé au trajet de signal portant un signal opérationnel; (iii) recevoir (106) un signal à spectre étalé réfléchi par le trajet de signal généré en fonction du signal de référence à spectre étalé; (iv) mettre en rapport (108) le signal à spectre étalé réfléchi avec le signal de référence à spectre étalé pour obtenir une corrélation correspondant à une caractéristique du trajet de signal.
