Abstract
A system for estimating an angle of arrival of a signal includes an object, a movable component that is movably coupled to the object, and at least first and second spaced-apart antennas coupled to the movable component. The system also includes a controller that is configured to estimate an angle of arrival of a signal based on a difference between a time the signal arrives at the first antenna and a time the signal arrives at the second antenna while the movable component is moving, and a difference between a frequency of arrival of the signal at the first antenna and a frequency of arrival of the signal at the second antenna while the movable component is moving.
