Abstract[English]
The present disclosure relates to methods, apparatuses and systems for joint passive target and active node targeting. The method comprises the steps of transmitting a first linear frequency modulated (LFM) signal, receiving a reflected signal, obtaining a first time of arrival (ToA) and a first angle of arrival (AoA) from the reflected signal, determining the position of the target from the first ToA and the first AoA, receiving, from the target node, a second LFM-based signal, the second LFM-based signal comprising a time offset and a second AoA, determining a second ToA from the second LFM-based signal, and obtaining the position of the target node from the second ToA, the time offset and the second AoA.[French]
La présente divulgation concerne des procédés, des appareils et des systèmes de ciblage de cible passive et de nœud actif conjoint. Le procédé comprend les étapes consistant à : transmettre un premier signal modulé en fréquence linéaire (LFM), recevoir un signal réfléchi, obtenir un premier temps d'arrivée (ToA) et un premier angle d'arrivée (AoA) à partir du signal réfléchi, déterminer la position de la cible à partir du premier ToA et du premier AoA, recevoir, en provenance du nœud cible, un second signal à base de LFM, le second signal à base de LFM comprenant un décalage temporel et un second AoA, déterminer un second ToA à partir du second signal à base de LFM, et obtenir la position du nœud cible à partir du second ToA, du décalage temporel et du second AoA.
