1. In an antenna system having a plurality of antenna elements, each for radiating and receiving electromagnetic signals, said system including means for providing signals to said antenna elements for radiation therefrom, means for detecting signals received by said antenna elements and means for controlling the phase of said radiated and said received signals, the improvement comprising:

  • means, including a position detector for determining the relative physical position of at least one of said antenna elements with respect to a nominal relative position for said antenna element in said antenna system;

    means for computing a phase correction associated with the difference between said relative physical position and said nominal relative position; and

    means for operating said phase control means to compensate for said computed phase correction.
