Abstract

L'invention concerne un procédé de télémétrie, caractérisé en ce qu'il comprend les étapes suivantes :(a) émettre une onde électromagnétique modulée en amplitude de sorte à la diriger sur une cible située à une distance d de la source électromagnétique ;(b) recevoir l'onde réfléchie par la cible ;(c) mesurer au moins un écart d'amplitude entre l'onde émise et l'onde reçue ;(d) calculer la distance d à partir de cet écart d'amplitude.L'invention concerne en outre un dispositif mettant en oeuvre ce procédé, ainsi que des applications possibles de ce procédé.The invention relates to a telemetry method, characterized in that it comprises the following steps: (a) emitting an electromagnetic wave modulated in amplitude so as to direct it on a target located at a distance d from the electromagnetic source; (b ) receive the wave reflected by the target; (c) measure at least one amplitude difference between the transmitted wave and the received wave; (d) calculate the distance d from this amplitude difference. The invention further relates to a device implementing this method, as well as possible applications of this method.
