Summary:This paper experientially examines heart rate estimation using a millimeter-wave vital sign radar, which can eliminate the body-motion components using two-beam technique. Measurement was conducted in an anechoic chamber using a 79 GHz 2 × 4 Multiple-Input Multiple-Output (MIMO) Frequency-Modulated Continuous-Wave (FMCW) radar. When the subject rocked his upper body at 1 Hz, the experimental result showed that this technique reduces the body-motion components by 40 dB and improves the heart rate estimation accuracy by 14.6 bpm compared to the case without this technique.
