Performance of an Angle-of-Arrival Estimator in the Presence of a Mainbeam Interference Source

Abstract

Mainbeam interferences presents a serious target tracking problem for array antennas. This report investigates a technique that is capable of providing information on target angle of arrival when a single interference source enters the antenna mainbeam. In-depth evaluation of the technique shows that its performance in angle estimation accuracy is comparable with that obtained by other more sophisticated methods, yet its implementation is relatively simple. The resultant angular estimation errors are quite close to the theoretical Cramer-Rao bounds previously derived.
