Reconstruction of heartbeat and respiration waveforms from waveform observed by mm-wave MIMO FM-CW radar

抄録

This research deals with the non-contact measurement of vital signals by mm-wave MIMO FM-CW radar. The radar observes the movement of the skin on the chest. This skin vibrates slightly under the influence of heartbeat and respiration. Since the radar observes the movement of the skin on the chest, the heartbeat and respiration information is mixed up. In this report, we attempt to separate the mixed signals into respiratory and heartbeat signals and reconstruct both waveforms.
