Abstract
Methods and systems for estimating an angle of arrival are provided. In an embodiment, a system for estimating angle of arrival includes a snapshot determining module configured to receive a signal from each antenna of an antenna array and to generate a snapshot vector including values based on the signals and an angle of arrival processing module configured to estimate an angle of arrival for the electromagnetic signal relative to the antenna array based on the snapshot vector. Each signal is representative of an electromagnetic signal incident on a respective antenna of the antenna array and each value is representative of a phase of a respective signal.
