Propagation aspects for RF fingerprinting at open areas over irregular terrain

Ray tracing simulations are used to investigate the RF fingerprinting in open areas over irregular terrain profiles. We show that these simulations can project the RF signature exclusiveness of an emitter location in space by means of received power, mean azimuth DoA and delay spread heat maps. Additionally, full-3D ray-tracing simulations allow us to investigate the amount of energy inside and outside the plane of incidence and to classify it according to the terrain profile type and LOS/NLOS. The methodology presented will permit evaluation of the traditional geometric method and the RF fingerprinting technique for position determination.
