Respiratory Rate Determination during Sleep by CW Doppler Radar

Abstract

Bioradiolocation is a remote method for diagnostics by means of a radar. In particular, it may be used for respiratory rate determination. In this paper we are going to present a developed algorithm for detection of movement artefacts in a bioradar signal and further signal processing to obtain an information about respiratory rates for persons with sleep apnea at different positions of a human body during sleep.
