Abstract
Source tracking for phased array systems is described herein. One processing device includes a transceiver to transmit or receive radio frequency (RF) signals via a plurality of antenna elements and a processor coupled to the transceiver. The processor executes a multi-angle source-tracking tool configured to determine and store a set of angle estimation values of an angle between the plurality of antenna elements and the second antenna, a set of confidence measurements, and at least one of an Area-of-Arrival (ARoA) value or an Area-of-Departure (ARoD) value based on the RF signals. Each of the set of confidence measurements indicates a confidence of an angle estimation value of the set of angle estimation values.
