Range–Doppler‐based centralised framework for human target tracking in multistatic radar

Positioning and Tracking of Multiple Humans Moving in Small Rooms Based on a One-Transmitter–Two-Receiver UWB Radar Configuration

“…Seeing that the non-cooperative (tag-free) positioning of a single moving person can be considered satisfactorily mastered and well documented in the UWB radar literature, let us look at how many human targets the term multiple usually refers to. If we consider only experimentally demonstrated results and no computer simulations, it can still be a single human [ 10 , 11 , 12 , 13 , 14 ], but more probably two people in motion [ 15 , 16 , 17 , 18 ] or three simultaneously moving human targets [ 19 , 20 , 21 ]. This indicates that obtaining high-accuracy human tracks in crowded scenarios of a real-world complex environment is still an open research area in the UWB radar community.…”

“…This paper aims to propose a sequence of steps that will allow multi-person localization and tracking with a single UWB radar equipped with the minimal antenna array needed for trilateration, i.e., one-transmitter–two-receiver configuration. Its localization accuracy is admittedly limited in comparison with spatially distributed antennas of multistatic radar [ 17 , 18 , 19 ], multiple-input multiple-output (MIMO) radar [ 38 , 39 , 40 ], or radar network [ 20 , 21 , 41 , 42 , 43 ]. On the other hand, thoughtfully chosen placement of antennas can increase the detectability of several humans moving in the small areas and additionally decrease the computational complexity of the signal processing methods applied e.g., for the deghosting solution.…”
