A system for monitoring physiology, having: a RADAR transmitter and a RADAR receiver； a state estimation module configured to process a returned RADAR signal to detect a presence of motion and set a motion state upon said presence of motion, said state estimation module configured to detect a presence of one or more physiological parameters including heartbeat and respiration, and said state estimation module configured to assign a still state or a concern state based on said presence of physiological parameters； a rate estimation module configured to estimate one or more estimated physiological rates including an estimated respiration rate and an estimated heart rate； and an alerting module configured to provide an alert if an alert value exceeds an alert value threshold, wherein the alert value is derived from at least one of the motion state, concern state, still state and the estimated physiological rates.
