本文对四种雷达传感器检测呼吸活动的能力进行了测试。特别是距离选通超宽带、CMOS超宽带、连续波相位检测和FMCW雷达。考虑到一个现实的情况下，雷达天线已指向胸部的呼吸对象和记录的信号已被比较与放置在胸部周围的压电带。然后，通过放置在离雷达天线不同距离处的振荡铜板，测试了雷达探测微小运动的能力。所有考虑的雷达都能够检测到与距离相关的分辨率的板块运动。
In this paper the ability of four radar sensors in detecting breath activity has been tested. In particular, range gating UWB, CMOS UWB, CW phase detecting, and FMCW radars have taken into account. Considering a realistic scenario, the radar antenna has been pointed towards the thorax of a breathing subject and the recorded signals have been compared with those of a piezoelectric belt placed around the thorax. Then the ability of the radars in detecting small movements has been tested by means of an oscillating copper plate placed at various distances from the radar antenna. All the considered radars were able to detect the plate movements with a distance-dependent resolution.
