Abstract
(EN) A system for radar interference mitigation, preferably including one or more transmitter arrays, receiver arrays, and/or signal processors, and optionally including one or more velocity sensing modules. A method for radar interference mitigation, preferably including transmitting a set of probe signals, receiving a set of reflected probe signals, and/or evaluating interference, and optionally including decoding the set of received probe signals and/ or compensating for interference.
(FR) L'invention concerne un système pour limiter les interférences radars, comprenant de préférence un ou plusieurs réseaux émetteurs, réseaux récepteurs et/ou processeurs de signaux et comprenant éventuellement un ou plusieurs modules de détection de vitesse. L'invention concerne également un procédé pour limiter les interférences radars, comprenant de préférence la transmission d'un ensemble de signaux de sonde, la réception d'un ensemble de signaux de sonde réfléchis et/ou l'évaluation des interférences et éventuellement le décodage de l'ensemble de signaux de sonde reçus et/ou la compensation des interférences.
