本文通过实验研究了天线辐射参数对2.4GHz多普勒雷达非接触式心率监测系统检测能力的影响。四种不同类型的贴片天线和阵列配置都在发射机和接收机侧实现。使用线性驱动器进行了广泛的实验，并报告了一些有趣的非平凡的结果。结果表明，在发射端采用线极化单片天线，在接收端采用圆极化天线阵，可以获得最高的信号质量和系统性能。在人体实验上的概念验证实验进一步验证了建议的结果。实验还表明，使用推荐的天线布置将使雷达的心率检测精度平均提高11%。

英文摘要：
  This paper presents an experimental study to evaluate the effects of antenna radiation parameters on the detection capabilities of a 2.4 GHz Doppler radar used in non-contact heart rate monitoring systems. Four different types of patch antennas and array configurations were implemented on both the transmitter and receiver sides. Extensive experiments using a linear actuator were performed and several interesting and nontrivial results were reported. It is shown that using a linearly polarized single patch antenna at the transmitter and a circularly polarized antenna array at the receiver results in the highest signal quality and system performance. Proof-of-concept experiments on human subjects further validated the suggested results. It was also shown that using the recommended antenna arrangement will boost the heart rate detection accuracy of the radar by an average of 11%.
