Real-time ultrawideband MIMO channel sounding

In this paper, we present a detailed description of the measurement setup and results obtained from a realtime ultrawideband MIMO channel sounding experiment. This channel sounding experiment was designed to perform remote detection of the vital signs of human subjects as well as tracking of mobile targets in an indoor environment. The paper also describes our antenna calibration setup and data processing for the UWB antenna arrays. We show in our analysis that the results from the real-time UWB MIMO channel sounding conveys information of small scale changes in the channel, which are due to the mobile target under observation. Finally, we conclude that the real-time UWB MIMO Channel sounding technique may be used for the localization and surveillance of humans and animals.
