Effect of Angle Detection on Respiration Vital Sign Measurement Using FMCW Radar

In implementing radar system for non-contact human respiration need to consider the radar placement in the monitoring area. The radar placement in the monitoring area may cause the measurement to be conducted with various angle detection. The effect of angle detection on respiration measurement using Frequency Continuous Wave Radar (FMCW) is reported in this paper. The laboratory experiments using 24 GHz FMCW radar were carried out in investigating the angle detection effect. This paper presents the results of respiratory detection using FMCW radar that was performed on several angle detection. Angle detection influences detection performance. For improving the detection accuracy, the correction is required.
