Estimation of Angle of Arrival with Two-Dimensional Circular and Nonuniform Arrays

Abstract

Positioning systems tasked with performing geolocation of objects have grown in importance in recent years as the demand for accurate position and spatial data has increased. Parameter estimation of the angle of arrival is a common approach used in positioning systems that has had great success. This paper presents the design and development of a computationally efficient angle of arrival estimation technique that is reconfigurable for changing requirements that different applications may impose. The theory explaining the method is outlined, along with field experiments and simulations to provide validation for the effectiveness and accuracy of the approach.
