  • Electronically scanned antenna arrays with reconfigurable performance
    Patent number: 10224627
    Abstract: An apparatus may include a plurality of antenna elements forming an antenna array. The apparatus may further include a beamformer that determines one or more of phase and amplitude shifts to cause the plurality of antenna elements to produce a beam in the direction of a target. The apparatus may further include a null limiter comprising dither circuits. The dither circuits may dither the one or more of phase and amplitude shifts by adding noise to cause a side lobe of the beam to increase above a threshold value. The dither circuits may be enabled by a control signal, and the dithered one or more of phase and amplitude shifts may be provided to the antenna elements to produce the beam in the direction of the target with the side lobes above the threshold value.

  • Adaptive array
    Patent number: 7317427
    Abstract: An adaptive antenna array has array elements arranged in element rows and element columns and subarrays arranged in subarray rows and subarray columns, for which the subarray phase centers have non-uniform spacing. The adaptive antenna array provides good detection and tracking performance when used in a radar system, while being inexpensive and easy to manufacture. A radar system and a method of adapting a radar array both employ the above described adaptive antenna array.
