Directionally Resolved UWB Channel Modeling for Environment-Aware Positioning

In this paper, we formulate a radio channel model for directionally resolved ultra-wideband radio measurements, which takes the directionality of a steerable antenna frontend into account. We outline a Figure of merit to assess the quality of specular multipath components (SMCs) for positioning applications, the signal-to-noise-and-interference-ratio (SINR), and perform an analysis thereof for a practical environment on the basis of a measurement campaign conducted in a parking house. The angle resolved analysis of the SINRs of various SMCs establishes a site specific model of the radio environment that can be leveraged for location-aware radio positioning and communication systems.
