Abstract
A method and a system for determining an in vivo transit distance and a corresponding transit time for an arterial pulse. An example system comprises a radar receiver connected to a processor to perform time-resolved measurements of reflections of wave pulses and to spectrally filter the reflections to select spectral components associated with the arterial pulse. The resulting signal samples are then organized into groups corresponding to different wave pulses, and the groups are processed to identify samples corresponding to a first arterial pulse point and a second arterial pulse point on the body of a subject, and the identified samples are further processed to determine the in vivo transit distance and the corresponding transit time for the arterial pulse. In some embodiments, a collection of arterial pulse points detected by the measurements may be mapped onto a reference constellation for a more-accurate determination of the in vivo transit distance.
