Abstract
Ultra Wide Band radar is a promising technique for remote vital signs monitoring. For home monitoring and consumer devices, FFC rules pose severe limits to the available band and the maximum transmitted power. In this paper vital signs (heartbeat and respiration rate) are monitored with a FCC compliant system; in this scenario, time of arrival variations are not sufficient to detect vital signs. Therefore, amplitude and phase modulation is investigated; both theoretical analysis and experimental results show that vital signs affect both the amplitude and the phase modulationFile in questo prodotto:
