Abstract: A microwave transceiver and feature extraction system is described. This system is adapted for measuring both electrical (ECG-related waveforms) and mechanical activity (heart sound and wall motion) of the heart and vessels, determining which signal features are related to which mechanical properties, and measurement of important hemodynamic parameters such as pressure, flow, and vessel's wall displacement. This system is non-invasive, portable, non-contacting and can remotely collect data at distances of
