A BEAM-SHIFTING TECHNIQUE FOR SIDE LOBE REDUCTION AND PATTERN SYNTHESIS.
Abstract
The idea of this method is to produce a narrow beam by using an aperture of convenient size with uniform illumination. By progressively phasing the aperture illumination this beam is shifted. Many beams are superposed and usually shifted in such a way that the maximum of each coincides with the zeros of all the others. By controlling the maximum amplitude of each beam, sidelobe reduction or pattern synthesis can be accomplished. Several examples are given. The results are indistinguishable from those of more involved methods. The method is extremely simple and gives a good feeling of the influence of each parameter in the resulting pattern. This is a very important feature because it makes possible an easy determination of the changes necessary to improve a synthesized pattern. This is illustrated in some of the examples. The method applies to discrete arrays as well as to continuously illuminated apertures. (Author)
