Performance Analysis of Angle of Arrival Algorithms Applied to Radiofrequency Direction Finding

Abstract

Radiofrequency (RF) interference threatens the functionality of systems that increasingly underpin the daily function of modern society. In recent years there have been multiple incidents of intentional RF spectrum denial using terrestrial interference sources. Because RF based systems are used in safety-of-life applications in both military and civilian contexts, there is need for systems that can quickly locate these interference sources. In order to meet this need, the Air Force Research Laboratory Weapons Directorate is sponsoring the following research to support systems that will be able to quickly geolocate RF interferes using passive angle-of-arrival (AoA) estimation to triangulate interference sources. This research studies the performance of the AoA estimation algorithms for an existing uniform linear antenna array. Four algorithms are studied and algorithm recommendations are made.
