Abstract
Technologies directed to are monitoring human vital signs with mmWave radars are described. One method sends a first signal having a first chirp that is a triangular-type chirp that increases in frequency for a first period and decreases in frequency for a second period and a second chirp that is a ramp-type chirp that increases in frequency for a third period. The method receives a second signal corresponding to the first signal. The method generates, using the first chirp and a first portion of the second signal, a third signal indicative of a human vital sign, such as a heart rate or a respiratory rate. The method measures a received signal strength indicator (RSSI) value of a second portion of the second signal at approximately 60 GHz. The method determines, using the RSSI value, a value indicative of oxygen-concentration in an ambient environment of the monitoring device.
