CA 2720871
A radar-based physio-logical motion sensor is disclosed. Doppler-shifted signals can be ex-tracted from the signals received by the sensor. The Doppler-shifted sig-nals can be digitized and processed subsequently to extract information related to the cardiopulmonary mo-tion in one or more subjects. The in-formation can include respiratory rates, heart rates, waveforms due to respiratory and cardiac activity, direc-tion of arrival, abnormal or paradoxi-cal breathing, etc. In various embodi-ments, the extracted information can be displayed on a display.
L'invention concerne un capteur de mouvement physiologique à base d'un radar. Les signaux à déplacement Doppler peuvent être extraits des signaux reçus par le capteur. Les signaux à déplacement Doppler peuvent être digitalisés et traités ensuite pour extraire l'information concernant le mouvement cardio-pulmonaire chez un ou plusieurs sujets. L'information peut comprendre les vitesses respiratoires, les vitesses du cur, les formes d'onde dues aux activités respiratoire et cardiaque, la direction de la respiration d'arrivée, anormale ou paradoxale, etc. Dans différents modes de réalisation, l'information extraite peut être présentée sur un affichage.
