Radar-Based Monitoring of Vital Signs


G. Paterniani et al.


Radar techniques aimed at health monitoring have been investigated recently and have gained sufficient interest as a potential technique for monitoring human vital signs. Radar technologies represent an emerging solution to promote human well-being in clinical environments. This is due to the accessibility of low-cost radar equipment, and to the development of radar architectures and signal processing methods that make it simple to use. The measurements obtained from diverse radar systems are analyzed through computers to determine breathing and heart activities of patients. This article presents recent developments in integrated radar technologies for modern monitoring applications. It focuses on a few representative works about integrated radar technology operating in continuous-wave mode or ultra-wideband pulse mode. This article builds the technical understanding of how radars can be used to monitor vital health signs. The benefits of the radar system to modern health solutions are clearly demonstrated through various examples of radar technology that are now in use along with the signal processing algorithms designed to accurately predict vital signs. In addition, the authors present some commercial application case studies and provide guidelines for the selection and deployment of radar equipment for monitoring vital signs. Furthermore, the article discusses the outlook of integrated radar solutions and the corresponding need for future semiconductor technologies, as well as some innovative characteristics of radar systems with health monitoring applications. Finally, it highlights the unique characteristics of radar systems and their potential applications in the field of medical diagnosis.
