AN ITERATIVE TECHNIQUE FOR REDUCING SIDELOBES OF CIRCULAR AND CYLINDRICAL ARRAYS.

Abstract

An iterative technique which allows the computation of low sidelobe current distributions for circular and cylindrical arrays, was developed and computer implemented. The method is described, and examples are shown of its use in calculating current distributions for circular arrays of 32 axial dipoles with half-wavelength element spacing. For such arrays of 2Q elements azimuth directivities only 0.5 dB less than the directivity of an order-Q Tchebycheff pattern with the same sidelobe level were obtained. (Author)
