2D-Multiple Signal Processing Approach to Human Orientation Monitoring Using Millimeter-wave FMCW Radar

Abstract

In recent years, unobtrusive continuous monitoring devices have
been subjects of research interest. These sensors enable remote
monitoring of human vital signs and activity levels, which can be
used in an expensive list of applications including the detection of
distracted driving, gait analysis, and fall detection - applications that
are highly dependent on information regarding the posture of the
subject under test. In this work, a method of human posture orientation estimation is proposed using a high frequency mmwave
(millimeter-wave) Frequency-Modulated Continuous Wave (FMCW)
radar.
