(54) Title (EN): METHOD AND APPARATUS FOR NON-CONTACT FAST VITAL SIGN ACQUISITION BASED ON RADAR SIGNAL
(54) Title (FR): PROCÉDÉ ET APPAREIL POUR L'ACQUISITION DE SIGNES VITAUX RAPIDE SANS CONTACT SUR LA BASE D'UN SIGNAL RADAR

(57) Abstract:
(EN): Various examples are provided for non-contact vital sign acquisition. Information can be provided regarding vibrations of a target using a radar signal such as, e.g., non-contact vital sign measurement. Examples include estimation of heart rate, change in heart rate, respiration rate, and/or change in respiration rate, for a human or other animal. Implementations can produce one or both rates of vibration and/or change in one or both rates of vibration for a target other than an animal or human experiencing two vibrations at the same time, such as a motor, a vehicle incorporating a motor, or another physical object. Some implementations can estimate the respiration movement in the radar baseband output signal. The estimated respiration signal can then be subtracted from radar signals in the time domain and, optionally, can be further enhanced using digital signal processing techniques, to produce an estimate of the heartbeat pulses.
(FR): La présente invention concerne, dans plusieurs exemples, l'acquisition de signes vitaux sans contact. Des informations concernant des vibrations d'une cible peuvent être fournies à l'aide d'un signal radar, telles que par exemple une mesure de signes vitaux sans contact. Les exemples comprennent l'estimation du débit cardiaque, le changement du rythme cardiaque, la fréquence respiratoire, et/ou le changement de la fréquence respiratoire, pour un être humain ou un autre animal. Certains modes de réalisation peuvent produire une ou deux vitesses de vibration et/ou un changement de l'une ou des deux vitesses de vibration pour une cible autre qu'un animal ou un être humain subissant deux vibrations en même temps, telles qu'un moteur, un véhicule incorporant un moteur, ou un autre objet physique. Certains modes de réalisation de l'invention permettent d'estimer le mouvement respiratoire dans le signal de sortie de bande de base radar. Le signal respiratoire estimé peut ensuite être soustrait des signaux radar dans le domaine temporel et, éventuellement, être en outre amélioré à l'aide de techniques de traitement de signal numérique, pour produire une estimation des impulsions de battement de cœur.
