Abstract

With the development of IoT and smart healthcare technologies, non-contact human vital sign detection holds significant importance in fields such as medical care, elderly care, and home nursing. This paper proposes a non-contact human vital sign detection method based on millimeter wave (MMW) radar. By analyzing MMW radar echo signals, real-time monitoring of respiratory and heartbeat signals is achieved. Experimental results demonstrate high accuracy and stability of the method, providing a new technical approach for non-contact vital sign monitoring.
