Abstract:
Ultra-Wideband (UWB) technology has emerged as a promising technology for use in precise indoor and outdoor localization systems, and has become handy for the rapidly growing fields of robotics and automation. The performance and accuracy of this technology are, however, affected significantly by multipath propagation, where the signals are exposed to reflection, scattering, and diffraction in the environment. This research embarks on improving UWB positioning accuracy by using spatial filtering techniques, with special emphasis on beamforming. A UWB localization model is developed for use in ranging for both indoor and outdoor environments. Theoretical modeling and simulations are then carried out to understand the influence of different environmental factors on the received UWB signals. Simulations are further carried out on the developed system, which utilizes beamforming to achieve spatial filtering of UWB signals. The experimental results show a significant improvement in UWB positioning accuracy compared to conventional non-beamforming methods.
