2-D localization, angular separation and vital signs monitoring using a SISO FMCW radar for smart long-term health monitoring environments
A single-input and single-output (SISO) frequency modulated continuous wave (FMCW) radar architecture is proposed and in vivo demonstrated for remote 2-D localization (range and angular information) and vital signs monitoring of multiple subjects. The radar sensor integrates two frequency scanning antennas which allow angular separation and enable determining a 2-D map (range versus angle) of a room environment from which people can be distinguished from objects and clutter.
