Description
Summary:In this paper, an innovative non-contact method is used to monitor vital signs, specifically focusing on heartbeat estimation through radar signals. Our approach utilizes a cross-correlation method based on a template function, effectively isolating cardiac information from phase-extracted radar signals during breathing. By accurately identifying heartbeat peaks over time, our method showcases the potential of radar technology for real-time vital sign monitoring in healthcare applications. Experiments conducted with a 24 GHz FMCW radar system, compared with synchronized ECG data, highlight the efficiency of our approach. Beyond demonstrating non-contact cardiac monitoring, our method brings respiratory arrhythmia to the forefront, providing valuable insights into the intricate dynamics of cardiac and respiratory patterns.
