01
Problem
The project analyzes AO/AC-related candidate timings in non-contact FMCW radar cardiac displacement waveforms aligned with ECG and SCG.
02
Architecture
Concurrent ECG/SCG/BGT60TR13C radar acquisition → ECG R-peak alignment → beat segmentation → phase-displacement and morphology candidate analysis → SQI/CTI export.
