Signal analysis: (a) WiFi CSI data (considering transmit antenna 1, receive antenna 1 and subcarrier 10); (b) UWB CFR data (considering the 10th CFR sample between node ‘0’ and node ‘3’ for UWB system 1 and nodes ‘1’ and ‘2’ for UWB system 2); (c) Velocity information extracted from Kinect sensor data and (d) PWR Doppler spectrogram extracted from surveillance channel ‘rx2’. Only a 196-second portion of exp018 is considered for the four synchronized modalities in this illustration.
