Proposed Signal Processing Method for Continuous Respiration Monitoring using UWB Radar

Respiration rate is one of the main vital signs that can measure a subject’s health condition. To measure respiration rate, the subject needs to attach some sensors to their skin. Due to its inconvenience, the contactless respiration monitoring method is studied today. The contactless respiration monitoring methods have a disadvantage in that the subject must stay static state during measurement. However, it is hard to stay static during measurement. To solve this problem, this paper proposes a method that can monitor the nonstatic subject’s respiration rate. As a result, our proposed method shows considerable accuracy with a nonstatic subject.
