Abstract
Technologies directed to are concurrent monitoring indoor oxygen-deficiency and human vital signs with mmWave radars described. One method sends a first signal having a first chirp having a triangular shape and a second chirp having a ramp shape. A frequency of the first signal is in a millimeter wave (mmWave) frequency range. The method receives a second signal corresponding to the first signal, the second signal comprising a first portion corresponding to the first chirp and a second portion corresponding to the second chirp. The method generates a third signal indicative of a human vital sign using the first chirp and the first portion. The method measures a value indicative of oxygen-deficiency in air using the second chirp and the second portion.
