Monitoring heart activity using ultra‐wideband radar [PDF]

Electronics Letters, 2019
This Letter focuses on extracting the heartbeat information using ultra‐wideband impulse radar, and a new method that can extract not only the heart rate but also the timing of the heartbeat with high accuracy is proposed herein. As the first step towards achieving this goal, radar pulses are projected towards a human body, and the reflected pulses are
