1. Apparatus for forming first and second frequency scanned beams of electromagnetic radiation, comprising:

  • an array of antenna elements;

    first and second inputs respectively receiving first and second pluralities of beam signals;

    first and second delay means respectively coupled with said first and second inputs, for delaying the beam signals as a function of frequency such that said first and second beams each scan over a target area; and

    means coupled between said antenna elements and said first and second delay means, for combining the beam signals from said first and second delay means, such that each of said antenna elements receives beam signals in said first and second pluralities thereof.
