Abstract: Systems and methods for monitoring vital signs (e.g. heartbeat, respiration) using FMCW millimeter wave radar are disclosed herein. A transceiver is used to transmit a first signal (FMCW) and receive a second signal (reflected). The transceiver transmits the second signal data to a computing device. A first set of radar data is generated by software on the computing device, based on the received second signal. A first set of Doppler interval measurements is obtained from the first set of radar data. A high Doppler response is obtained from the first set of Doppler interval measurements and vital sign data is extracted from the high Doppler response. Advantages include the use of Doppler frequencies which are free to use according to FAA specifications; living organisms (subjects) are not affected by the radiation or the transmission path; and a subject may be remotely monitored without requiring physical access.
