Abstract

Un signal de réception provenant du transpondeur (8-13) met en activité la station d'interrogation de manière à transmettre un signal d'activité limité dans le temps à une première fréquence porteuse, le transpondeur (8-13) envoyant à la réception du signal de mise en activité, un signal de réponse avec une fréquence égale à la seconde fréquence porteuse, avec une durée égale à celle du signal de mise en activité, ce signal de réponse pouvan contenir un code d'information/statut, et le temps entre la transmission du signal de mise en activité et la réception du signal de réponse est mesuré pour calculer la distance entre la station d'interrogation et le transpondeur.A reception signal from the transponder (8-13) activates the interrogation station so as to transmit a time-limited activity signal at a first carrier frequency, the transponder (8-13) sending to reception of the activation signal, a response signal with a frequency equal to the second carrier frequency, with a duration equal to that of the activation signal, this response signal may contain an information / status code, and the The time between the transmission of the activation signal and the reception of the response signal is measured to calculate the distance between the interrogation station and the transponder.
