Vital Signs Monitoring via Radio Reflection

Abstract

One method for monitoring periodic motion of one or more subjects uses signal reflections from the subjects. The method includes transmitting a transmit signal from a transmit antenna and receiving a receive signal at one or more receive antennas. The received signal includes a combination of multiple reflections of the transmitted signal, at least some of which are associated with the subject. The received signal including these reflections is processed to determine an estimate of the fundamental frequency of the periodic motion.
