Background:

Vital sign monitoring is crucial for healthcare.
Body movement during monitoring can degrade signal quality.
Existing radar methods struggle with movement artifacts.

Purpose of the Study:

To develop a radar-based vital signal detection system robust to body movement.
To improve signal-to-noise ratio (SNR) in vital sign detection.
To leverage multiple radars with different lines-of-sight (LOS) for enhanced accuracy.

Main Methods:

Utilized continuous-wave (CW) radar systems operating at different frequencies (5.8 GHz band) to minimize signal coupling.
Employed two adjacent radars with distinct LOS to capture asymmetrical organ movement (lungs, heart).
Developed a correlation technique to reinforce differences in movement signals, reducing noise.

Main Results:

The proposed multi-radar system achieved a mean accuracy of 97.8% in vital sign detection.
Successfully monitored subjects moving at velocities up to 53.4 mm/s.
Demonstrated significant reduction in body movement effects on vital signal detection.

Conclusions:

The multi-radar approach effectively mitigates signal degradation caused by body movement.
Correlating signals from radars with different LOS enhances vital sign detection accuracy.
This method offers a promising non-contact solution for remote vital sign monitoring.
