Indoor Human Tracking with Millimeter-Wave Minimum Redundancy MIMO Radar

Array radar needs enough array length to realize high angular resolution. However, it takes cost to increase elements physically. Recently, Minimum Redundancy Multiple- Input Multiple-Output (MR-MIMO) was proposed to increase the number of virtual elements efficiently. Further improvements by using Khatri-Rao (KR) transformation in the case of incoherent waves were also proposed. In this paper, we show experimental results on indoor human tracking with millimeter-wave MR- MIMO radar to verify the improvements of resolution and tracking performance in comparison with the results by a conventional MIMO radar.
