  • Patent number: 11988700
    Abstract: An antenna calibration system and method utilizes both computer electromagnetic modeling and actual test fixture measurements for calibrating the antenna or multiple antennas in an array. Use of the test fixture measurements enables the calibration technique to account for design nuances or imperfections in each respective antenna to enable that particular antenna to be more accurately modeled for calibration without having to physically maneuver the platform to calibrate the antenna that is to be installed thereon. Use of computer electromagnetic modeling techniques then account for these design nuances or imperfections to provide improved modeling for calibrating the antenna on a platform prior to moving the platform with the antennas on the platform.

  • Patent number: 11973268
    Abstract: This document describes techniques, apparatuses, and systems for a multi-layer air waveguide with layer-to-layer connections. Each pre-formed layer of the air waveguide is attached to at least one other pre-formed layer by a mechanical interface. The mechanical interface may be a stud-based interface, a snap fastener-based interface, a ball-and-socket based interface, or a pressure contact interface utilizing irregular roughed surfaces of each pre-formed layer. The mechanical interfaces of the pre-formed layers structurally hold the air waveguide together and electrically couple all of the pre-formed layers. In this manner, the cost of manufacturing the air waveguide antennas may be less expensive than previous manufacturing processes.

  • Patent number: 11965974
    Abstract: Disclosed is an approach to improve data collection for a radio-based positioning system. The disclosed approach may involve processor(s) (e.g., of positioning server(s) and/or of a mobile device) obtaining radio data associated with the mobile device, where the radio data is collected while the mobile device is located within a particular vehicle during a time of commute. The processor(s) may determine a particular location of the particular vehicle representing where the particular vehicle is or was located during the time of commute. And the processor(s) may then use the particular location of the particular vehicle to geo-reference the radio data collected while the mobile device is located within the particular vehicle during the time of commute.

  • Patent number: 11959995
    Abstract: A PLL has a tunable resonator including an inductance and variable capacitance coupled between first and second nodes, and capacitances coupleable between the nodes. A control node is coupled to the variable capacitance and receives a control signal for tuning the resonator. A biasing circuit biases the resonator to generate an output. A PFD circuit senses timing offset of the output with respect to a reference and asserts first or second digital signals dependent on the sign of the timing offset. A charge pump generates the control signal based on the first and second digital signals. A timer asserts a timing signal in response to a pulse sensed in a reset signal and de-asserts the timing signal after a time interval. A calibrator couples selected capacitances between the first and second nodes as a function of the second digital signal, in response to assertion of the timing signal.

  • Patent number: 11953617
    Abstract: A system and method for a multi-panel multi-function active electronically scanned array (AESA) radar operation receives radar commands from individual aircraft systems and segments a plurality of AESA panels fixed (at variable azimuth/elevation about the aircraft) into a plurality of subarrays to carry out each individual function commanded by the individual aircraft system. Dependent on aircraft status and phase of flight, the and individual AESA are designated for use and the subarrays are sized based on desired radar function at the specific phase of flight and specific threat associated with the phase. The system dynamically shifts the designated AESA, subarray size, beam characteristics, power settings, and function to enable multiple simultaneous function of the suite of AESA panels.
