Abstract

This study aligns ECG, SCG, and FMCW radar signals to ECG R-peaks and analyzes morphology-based AO/AC candidate timing across 848 corresponding beats.

Research Problem

The work studies a repeatable procedure for analyzing valve-event-related candidate timings in non-contact FMCW radar cardiac displacement waveforms.

System Architecture

The pipeline uses concurrent ECG, SCG, and BGT60TR13C radar acquisition, ECG R-peak alignment, beat segmentation, and radar morphology candidate analysis.

Methodology

One participant, 100 Hz, and 600 seconds of concurrent acquisition. Of 853 ECG R-peaks, 848 matched beats support comparisons between SCG references and radar AO/AC candidate timings.

Results

600 seconds of concurrent ECG, SCG, and radar acquisition; candidate timings across 848 corresponding beats.
