Pulse transit time-based method for distance measurement employs a complex multi-parametric modulation of emitted pulses with adaptive control of the parameters of modulation. An evaluation of the pulse transit time-variable's observability in a measuring cycle is used as an input of the adaptive control loop. The achieved special pattern of received pulses provides for obtaining a vector of characteristic elements on the pattern with low sensibility to active and passive disturbances present during measurement. These characteristic elements are used by the method for the accurate measurement of the pulse transit time, and consequently, for the calculation of the distance between the emitter of pulses and the target.

L'invention concerne un procédé de mesure de distances, basé sur le temps de transit des impulsions, utilisant une modulation multiparamétrique complexe des impulsions émises, avec contrôle adaptatif des paramètres de modulation. Une évaluation de l'observabilité, dans un cycle de mesure, de la variable des temps de transit d'impulsions, est utilisée comme entrée de la boucle de commande adaptative. Le modèle particulier obtenu des impulsions reçues permet d'obtenir un vecteur d'éléments caractéristiques des modèles de faible sensibilité des perturbations actives et passives se présentant durant la mesure. Ces éléments caractéristiques sont utilisés par le procédé, ce qui permet d'avoir une mesure précise du temps de transit d'impulsions, et de calculer la distance entre l'émetteur d'impulsions et la cible.
