Description
Radar can measure heart rate without touching the body, but sorting out several people at once is hard. Dong and co-authors propose a full scheme for that case. A precise range method locates each person, an antenna array with a root-MUSIC algorithm finds their angles, and a chained signal-cleaning method pulls out each heartbeat.
A faster version of an interpolation method then reads the heart rates with about 60 percent less compute time. In six test setups, including people packed close and blocking each other, the scheme kept its average error under 2.6 beats per minute. The authors see uses in health monitoring and other fields.
