  • Estimating angle measurements for source tracking using a phased array system
    Patent number: 11397256
    Abstract: Example apparatus, systems and methods use a receiver of a first device to receive from a second device, radio frequency (RF) signals. Embodiments use a processor of the first device to determine, based on the RF signals, a set of angle-estimation values of an angle between a plurality of antenna elements of one of the first device and the second device and an antenna element of the other of the first device and the second device, and a set of confidence measurements. Each of the set of confidence measurements indicates a confidence of an angle-estimation value of the set of angle-estimation values.
    Type: Grant

  • Estimating angle measurements for source tracking using a phased array system
    Patent number: 10746864
    Abstract: A method includes using a receiver of a first device, receiving from a second device, radio frequency (RF) signals. The method also includes using a processor of the first device, determining and storing, based on the RF signals, a set of angle-estimation values of an angle between a plurality of antenna elements of one of the first device and the second device and an antenna element of the other of the first device and the second device, a set of confidence measurements, and at least one of an Area-of Arrival (ARoA) value and an Area-of Departure (ARoD) value. Each of the set of confidence measurements indicates a confidence of an angle-estimation value of the set of angle-estimation values.

  • Estimating angle measurements for source tracking using a phased array system
    Patent number: 9989633
    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.
