Bioradar-based Developer Kit noncontact breathing detection technology has been widely studied due to its superior detection performance.In this paper, a breath detection mechanism based on the change in radar cross section (RCS) is proposed by using a forward scatter radar and the deduction of the mathematical model of the received signal.Furthermore, we completed human breathing detection experiments in an anechoic chamber and in an ordinary chamber; we obtained the breathing rate through envelope detection in cases where the human orientation angle was 0, 30, 60, and 90°.The analysis of the measured data shows that the theoretical model fits well with the measured results.Compared with the existing single-base radar detection schemes, the proposed scheme can detect human Seats respiratory rates in different orientations.
