基于接触的正交多普勒雷达心脏运动检测面临着I/ q形成的非弧星座的挑战。本文提出了一个假设，即这种复杂的星座不是由一个而是由两个运动目标形成的。双运动模型可以很好地解释基于接触的多普勒雷达在心脏周期中检测心房和心室的运动。在这项工作中，提出了双运动模拟和幻影测量，验证了房室运动是I/Q基带信号转录复杂非弧形星座的原因。它首次提供了基于接触式多普勒雷达测量实际心脏运动的证据。
Contact-based cardiac motion detection using Quadrature Doppler radar faces a challenge of the I/Q-formed non-arc constellation. In this work, a hypothesis is brought forward that such complicated constellation originates from not one, but two moving targets. The dual-motion model may very well explain that contact-based Doppler radar detects both atrium and ventricle motions during cardiac cycles. In this work, dual-motion simulation and phantom measurements are presented, verifying that the atrial-ventricular motions are the reason that I/Q baseband signals transcribe a complex non-arc constellation. It offers the first evidence that contact-based Doppler radar measures actual heart motion.
