  • Simultaneous nulling and beamfocusing from disparate antennas
    Patent number: 10601479
    Abstract: In an antenna array, signals may be manipulated to increase coherency at certain locations (beamfocusing) and reduce or cancel the signals at other locations (nulling). This is accomplished by multiplying the signals received or transmitted by the set of antennas by a weight vector that is generated by determining a covariance matrix based on a vector representing signals at the set of antennas, vectors representing the desired beamfocusing and nulling locations, and a desired nulling depth.
    Type: Grant
    Filed: April 8, 2019
    Date of Patent: March 24, 2020
    Assignee: THE BOEING COMPANY
    Inventors: Peter S. Wittenberg, Debra P. Michal
