Efficient UWB Indoor Localisation Using a Ray-tracing Propagation Tool

A novel method of applying Ray Tracing to the problem of Ultra-wide Band (UWB) indoor userlocalization is presented. This novel method for UWB localization is based on correlation between the received signal and a database of pre-computed ray-traced signals computed on a search curve. In the absence of real data the technique is validated by generating synthetic received signals using ray tracing plus Rayleigh distributed random multipath clusters as well as random amplitude and delay factors which account for database uncertainty. Results are presented that indicate that acceptable location and tracking performance can be achieved with a single sensor.
