Abstract:

A formulation for synthesizing an optimum nonuniformly spaced but symmetrical array by adjusting both the amplitude excitations and element spacings is given. This is accomplished by applying Haars theorem which is known in a branch of mathematics. It is shown that the solution obtained according to the method proposed here is optimum in the senses that, with respect to a chosen set of element spacings, 1 the maximum deviation between the synthesized and desired patterns is minimized, 2 the side lobes can be made approximately equal and their level minimum for a specified beamwidth, 3 the side lobe level and beamwidth are not seriously constrained so that a solution better than the Dolph-Chebyshev array may be possible, 4 a minimum number of elements required to synthesize a desired pattern may be determined, and 5 the solution can be unique.
