Abstract

L'invention concerne des procédés et un appareil de communication, qui peuvent être appliqués à une détection bistatique pour transmettre un premier signal de détection et un second signal de mesure de trajet de référence pour améliorer la précision d'un résultat de télémétrie cible, ainsi que la précision de détection. Un procédé comprend les étapes suivantes : un premier appareil de communication transmet à un second appareil de communication des premières informations de configuration, qui sont utilisées pour configurer la transmission d'un premier signal et d'un second signal pendant une première période de temps, et transmet le premier signal de détection et le second signal de mesure d'un trajet de référence, de telle sorte que le second appareil de communication puisse recevoir un signal d'écho du premier signal et du second signal sur la base des premières informations de configuration, obtenir également, sur la base du signal d'écho du premier signal, un retard temporel (représentant la distance jusqu'à une cible) correspondant à un trajet de réflexion, et obtenir, sur la base du second signal, un retard temporel correspondant à un trajet de référence, de façon à éliminer, sur la base des deux retards temporels, les effets indésirables d'une erreur de synchronisation temporelle entre l'extrémité de transmission et l'extrémité de réception sur le retard temporel correspondant au trajet de réflexion, ce qui permet d'améliorer la précision d'un résultat de télémétrie cible, ainsi que la précision de détection.
