Abstract
A method and system to determine angle of arrival of a target include one or more transmitters, one or more receivers, and one local oscillator to provide a local reference signal each in two or more transceiver nodes. The system also includes a controller to determine obtained phase differences for each of the two or more transceiver nodes. Each of the obtained phase differences is between a signal transmitted by one of the one or more transmitters and received by one of the one or more receivers of a same one of the two or more transceiver nodes. The controller estimates the angle of arrival of the target based on the obtained phase differences determined for the two or more transceiver nodes.
