Abstract

This project is focused on implementing source location algorithms to find the direction of arrival of transmitted radio frequency signals on an array of receivers. The MuSIC (multiple signal classification) algorithm is used, as well as a variant, smooth-MuSIC, which mitigates the effects of multipath interference. Beamforming techniques, which combine temporal and spatial filtering, are also used to find the direction of arrival. These strategies minimize the transmission power needed to send a signal. Further work building on this research can implement directional transmission and receiving with beamforming, which yields many advantages including minimized signal interception. The results from this research can be used to make adaptive arrays of receivers that minimize noise or interfering signals, as well as address universal communications issues on a cost-effective platform.
