This invention is a system and method of locating a target (5) using distributed antenna. The antenna consists of several receiving elements (4, 6, 6) in known locations. At least one of the receiving elements is also a transmitter (4) and transmits an interrogation signal (7) to a target (5). The return signal (8) from the target (5) is received by a plurality of receiving elements (4, 6, 6) and the target's position is calculated using the time of arrivals of the reply signal (8) and the round trip delay between the transmission of the interrogation signal (7) and the reception of the subsequent reply signal (8).
L'invention concerne un système et un procédé de localisation d'une cible (5) au moyen d'une antenne répartie. Cette antenne comprend plusieurs éléments de réception (4, 6, 6) situés à des emplacements précis. Au moins un desdits éléments de réception est également un émetteur (4) qui émet un signal d'interrogation (7) vers une cible (5). Le signal de retour (8) émit par la cible (5) est reçu par une pluralité d'éléments de réception (4, 6, 6) ; la position de la cible étant calculée sur la base du temps d'arrivée du signal de réponse (8) et du temps de transmission A/R entre la transmission du signal d'interrogation (7) et la réception du nouveau signal de réponse (8).
