1. A method of generating a beam pattern covering a region of interest, said method comprising:

  • a) generating a first set of polarized beams having a first size, each beam in said first set of polarized beams occupying a portion of a frequency spectrum;

    b) generating second set of polarized beams having a second size, each beam in said second set of polarized beams occupying a portion of the frequency spectrum;

    c) projecting said first set of polarized beams and said second set of polarized beams in an irregular pattern onto a region of interest to create a beam pattern of projected beams having at least two overlapping projected beams, each of said projected beams being non-interfering with any adjacent projected beam; and

    wherein said first size and said second size lie in the range of approximately 0.3 to 0.6 degree half angles.
