RF-Heartbeat: Robust and Contactless Heartbeat Monitoring Based on FMCW Radar
View through CrossRef
We propose RF-Heartbeat, a robust heartbeat monitoring system based on
FMCW radar, enabling accurate inter-beat interval (IBI) estimation.
Dynamic programming is implemented to improve the robustness of the
template matching algorithm. Template matching requires a high
similarity of heartbeat shape and suffers from shape variation of
heartbeat signal obtained by radar. With heartbeat signal, generated
template, and heart rate variability (HRV) prior knowledge, global
optimal heart segmentation can be achieved to solve this problem. In
addition, an optimal range bin selection algorithm is proposed.
Therefore, when the user is in different positions and postures,
RF-Heartbeat can always obtain high-quality heartbeat signals.
