Abstract

This study presents a novel approach to monitoring respiration rate using frequency modulated continuous wave (FMCW) mm-wave radar, aiming to overcome the limitations of traditional non-contact method. 14 participants were involved in an experiment involving alternating periods of stillness and left-right continuous body shaking. Data analysis involved non-negative matrix factorization (NMF) and template matching techniques. Respiration measured by radar were compared with ground truth measurements. Results demonstrated accurate respiration detection even during continuous body movement, with significant correlation observed between radar-based and ground truth measurements. This study pioneers radar-based respiration monitoring under continuous body movement conditions, offering promising implications for practical applications.
