Design and evaluation of remote tracking heart rate measurement based on millimeter-wave FMCW radar

Abstract

In recent years, due to the development of radar technology, the research of the remote heart rate measurement system has matured. However, most subjects in previous studies were at a stationary state during the experiment. In contrast to traditional radar-based heart rate measurement methods, this article proposed a novel trackable measurement method. We consider the FMCW radar module placed on a rotary stand with a stepping motor. The subject’s position is calculated by radar signal processing to drive the corresponding rotation of the stand. The results of the simulations prove the validity of the proposed solution.
