我们演示了使用超宽带雷达系统精确远程测量心跳。尽管大多数传统系统使用连续波或脉冲无线电系统进行远程生命监测，但连续波会受到非平稳杂波的影响，而脉冲无线电系统无法检测心跳。我们的超宽带雷达系统具有这些系统中间的适中分数带宽，即使在动态环境中，也能抑制杂波并提高准确测量心率的灵敏度。使用超宽带雷达和心电图同时测量参与者的生命信号，揭示了雷达系统在测量随时间变化的心率方面的高精度。
We demonstrate an accurate remote measurement of heartbeats using an ultra-wideband radar system. Although most conventional systems use either continuous waves or impulse-radio systems for remote vital monitoring, continuous waves suffer from non-stationary clutters, while impulse-radio systems cannot detect heartbeats. Our ultra-wideband radar system has a moderate fractional bandwidth intermediate of these systems, resulting in both the suppression of clutters and high sensitivity in measuring accurate heart rates even in a dynamic environment. A simultaneous measurement of the vital signal of a participant employing the ultra-wideband radar and electrocardiography reveals the high accuracy of the radar system in measuring the heart rate varying over time.
