An experimental study: The sufficient respiration rate detection technique via continuous wave Doppler radar

Abstract

In this paper, we present the experimental study based on filtering techniques to extract essential vital signals such respiration rate (RR) using continuous wave (CW) Doppler radar sensor. Due to the fact that the CW Doppler radar offers very high sensitivity towards minor movements, based on this technology, various filtering techniques were introduced and the detection rate was compared to the reference devices to conclude the leading method for the respiration rate detection.
