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
A comparison between ceiling-mounted FMCW, IR-UWB and Wi-Fi radar for in-bedroom human activity monitoring and sleep interruption detection
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.
意义：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。
