Single-channel radar-based indoor localization with passive reflectors.

Indoor localization has seen an emerging interest over the last years. As Global Navigation Satellite System (GNSS) signals cannot be used indoors, dedicated systems have to be deployed for indoor localization. 
Indoor positioning systems (IPS) based on millimeter (mm) waves offer high accuracy by using the ultra-wideband (UWB) approach, i.e. waveforms with large bandwidth. However, current UWB systems suffer from high system complexity and cost. We propose a millimeter wave indoor localization system based on active radar sensing of local passive reference points (LRPs) that promises highly accurate and reliable indoor localization at low system cost. This system shall be used to navigate autonomous mobile robots (AMRs) in indoor environments.
