天花板安装的FMCW、IR-UWB和Wi-Fi雷达在卧室人体活动监测与睡眠中断检测中的比较研究

为什么重要为医疗环境中的射频传感技术选型提供直接对比依据,揭示性能与鲁棒性的权衡,指导开发者根据部署需求选择合适技术。

摘要显示,该研究在相同条件下比较了天花板安装的FMCW、IR-UWB和Wi-Fi雷达用于人体活动识别和睡眠监测。使用20名参与者在六种房间布局下的同步记录,以相同CNN评估,IR-UWB在跨受试者活动识别中性能最高(宏F1 89.0%),FMCW对未见房间布局泛化最佳(83.8%),睡眠监测所有技术均超92%。结果揭示识别性能与环境鲁棒性间的权衡。

This paper presents a controlled comparison of ceiling-mounted FMCW, IR-UWB, and Wi-Fi sensing for human activity recognition and sleep monitoring, using synchronized recordings from 20 participants across six room layouts. IR-UWB achieved the highest cross-subject activity recognition (89.0% macro F1), while FMCW generalized best to unseen layouts (83.8%), and all technologies exceeded 92% macro F1 for sleep monitoring.
