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.
