本文综述了利用多普勒雷达提取心跳间隔的方法。单通道连续波雷达虽然结构和信号处理简单，但这种方法对被测对象的位置非常敏感，可能导致心率加倍，或者心脏和呼吸频率之间的耦合。正交无线电架构被用于克服这一局限性。还探索了使用线性和非线性解调方法来提取心跳间隔。
In this paper heartbeat interval extraction methods using Doppler radar are reviewed. While single channel CW radar offers simple architecture and signal processing, this method is very sensitive to subject position and may result in rate doubling, or the coupling between heart and respiratory rates. Quadrature radio architecture is used to overcome this limitation. The use of linear and non-linear demodulation methods was explored for heartbeat interval extraction.
