Digital IF phase-tracking doppler radar for accurate displacement measurements and vital signs monitoring

© 2017 IEEE. A Digital IF Phase-Tracking Doppler radar is presented for accurate displacement measurements and vital signs monitoring. This novel architecture implements a digital Phase-Locked-Loop (PLL) in phase demodulator configuration to extract the phase modulation caused by a moving target without requiring the small-angle approximation condition and solving the null-point issue. This facilitates the accurate measurement of a target's motion. Experimental results successfully demonstrated the feasibility of the proposed approach.
