Abstract: “There has been research interest in using the micro Doppler effect for contactless measurements of human respiration. Most of the research assumes that the test subject remains stationary. The purpose of this paper is to detect a respiration signal from a walking human. This work is at an early stage, and MATLAB model for a walking human with respiration movement was used, instead of recreating an actual human walking case. The results from this study show that a respiration signal can be successfully extracted from a walking human model.”
