Proximity sensors have been developing through the last decades.
Adopting a radiation source and analyzing the reflected signal,
obstacles and surroundings can be sensed and detected from a distance
without contact. The mm-wave radar systems provide considerable
potential in vital sign detection compared to the other proximity
sensing choices based on audio and ultrasonic waves or optical
signaling. In this study, a 60 GHz radar system was employed for
contactless vital sign detection, such as respiration and heartbeat
rate. The potential of the system in measuring through the materials was
studied in various transmission situations. Three different methods
were examined for preparing the phase information, and a clinically
certified heartbeat rate measurement tool analyzed the accuracy of the
results. The suggested algorithm can scan the region in the radar field
of view and capture exceptional features like the heartbeat rate with a
median accuracy of 96.22%.
