Abstract: A radar stethoscope system (12) and method for respiration and heart sound assessment is provided. Embodiments present a method to measure acoustics related to breathing and heartbeat sounds using small-scale radars. Acoustic data derived from the radar return measurements can be based on phase changes of the radar return measurements over a period of time. The radar stethoscope (12) can capture and identify respiratory and heart acoustics as traditionally captured by a clinical stethoscope. Using advanced radar processing algorithms, these acoustic signals can be recovered from a distance and without making contact with the patient (14).
