Current technology trends, such as ubiquitous computing and calm technology, call for novel unobtrusive sensors. The commonly used heart rate monitoring techniques require direct contact to the patient which makes the patient well aware of the sensors. In this paper, a novel method for detecting the distance of an approaching patient and for measuring his or her heart rate with a microwave Doppler radar is presented. This enables a truly non-contact and unobtrusive measurement. In addition, the measurement can be performed even through thick clothing. Furthermore, the patient does not need to be aware of being monitored since the method enables measurement to be started automatically as the patient approaches the sensor.
当前的技术趋势，如普适计算和平静技术，需要新型的非侵入式传感器。常用的心率监测技术需要与患者直接接触，这会使患者清楚地意识到传感器的存在。本文提出了一种利用微波多普勒雷达检测接近患者的距离并测量其心率的新方法。这实现了真正的非接触式和非侵入式测量。此外，即使隔着厚衣服也能进行测量。而且，由于该方法能在患者靠近传感器时自动开始测量，患者无需意识到自己正在被监测。
