Human vital sign detection using compressive sensing

Abstract

Non-invasive detection of human vital signs such as the respiratory rate, motion, etc. is important for both commercial and military applications. Some examples are disaster rescue services, health monitoring, homeland security, and urban warfare. Different radar systems have been considered for these applications. Mainly, these fall under three categories: continuous wave (CW) Doppler radar, UWB radar, and stepped-frequency (SF) CW radar. While the SFCW radar systems have advantages over both CW and UWB radar systems, they typically suffer from long data acquisition time, which can lead to aliasing while capturing scattered signals.
