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

From 600 seconds of concurrent acquisition, 848 corresponding beats were assembled for AO/AC-related candidate timing analysis.

Results

I concurrently acquired ECG, SCG, and radar for 600 seconds and analyzed candidate timings across 848 corresponding beats.

Next step

The current results are AO/AC candidate timings derived from radar morphology. Extending them to direct valve imaging or clinical valve detection requires follow-up comparison with independent physiological measurements.
