In this paper an ultra-wideband 80 GHz FMCW-radar system for contactless monitoring of respiration and heart rate is investigated and compared to a standard monitoring system with ECG and CO(2) measurements as reference. The novel FMCW-radar enables the detection of the physiological displacement of the skin surface with submillimeter accuracy. This high accuracy is achieved with a large bandwidth of 10 GHz and the combination of intermediate frequency and phase evaluation. This concept is validated with a radar system simulation and experimental measurements are performed with different radar sensor positions and orientations.
本文研究了一种用于非接触式呼吸和心率监测的超宽带80GHz调频连续波(FMCW)雷达系统,并将其与以心电图和二氧化碳测量为参考的标准监测系统进行了比较。新型FMCW雷达能够以亚毫米精度检测皮肤表面的生理位移。这种高精度是通过10GHz的大带宽以及中频和相位评估的结合来实现的。该概念通过雷达系统仿真得到验证,并在不同雷达传感器位置和方向上进行了实验测量。
