Multistatic RADAR Sensing for Activity Monitoring of Daily Living Simultaneously in Multiple Subjects

The dataset involves monitoring daily living activities simultaneously for multiple subjects in an office environment. Radiofrequency (RF) sensing was utilized to capture distinct fluctuations in channel state information resulting from both single and multiple activities. The data collection setup consists of one USRP device and two omnidirectional antennas. One omnidirectional antenna within the USRP (X300) functioned as the transmitter, while the other acted as the receiver. The USRP was connected to an All-in-One PC featuring an Intel(R) Core (TM) i7-7700 CPU operating at 2.45 GHz and equipped with 64 GB of RAM. LabVIEW enabled communication with the USRP device. The USRPs are based on the National Instrument (NI) X310/X300 models, linked to a single PC via 1G Ethernet connections, and include extended bandwidth daughterboard slots covering DC–6 GHz with up to 120 MHz of baseband bandwidth.

本数据集旨在对办公环境中多名受试者的日常活动进行同步监测。射频传感（Radiofrequency, RF）技术被用于捕捉由单人及多人活动引发的信道状态信息中的显著波动。数据采集装置由一台USRP设备和两根全向天线组成。USRP（X300）内置的一根全向天线作为发射器，另一根则作为接收器。该USRP设备连接至一台一体机（All-in-One PC），其搭载Intel(R) Core(TM) i7-7700 CPU（主频2.45 GHz）及64 GB内存。LabVIEW软件用于实现与USRP设备的通信。USRP设备基于美国国家仪器（National Instrument, NI）X310/X300型号，通过1G以太网连接至单台PC，并包含扩展带宽子板插槽，覆盖直流（DC）至6 GHz频段，基带带宽最高可达120 MHz。
