This thesis investigates a method of tracking remote transmitters using multipath localization fingerprints generated by a ray tracing simulation. Radio wave propagation phenomena in a dense urban environment can be simulated using publicly available mapping data and 2-D ray tracing techniques when the receivers and transmitters are found to be approximately co-planar. OpenStreetMap (OSM) building data is used to model the area of interest, and frequency of arrival (FOA) localization fingerprints are generated virtually along a grid. These fingerprints are then used to estimate the origin of incoming signals. Simulation of this method using three receivers and a 10 m square grid demonstrates a simulated localization accuracy within 15 m. Taking things a step closer to reality, an attempt to validate the ray tracing simulation is made. Validation is presented in the form of experimental results for a set of trials along with a statistical comparison to simulation results. A significant positive correlation between the experimental and simulation results is found and detailed. Finally, the tracking method described is applied to real collected signal data and the results discussed.
