ECG vs. Single-Antenna System for Heartbeat Activity Detection
Résumé
This paper presents a single antenna Doppler system for contactless heartbeat monitoring. The proposed system, based on using a vector network analyzer, is tested at 16 GHz frequency for different transmitted power levels between 0 and -25 dBm. Both heartbeat rate and heart rate variability are extracted from the signals obtained with the Doppler system and compared to simultaneous ECG signals.
