Application of aperture orthogonal polynomials method for synthesis phased array antennas

The article presents some methods of construction of nonequidistant phased array antennas (PAA). The first is a statistical allocation of elements under the determined law. The second-layout of elements under the law of simple numbers avoids a phase difference equal 2/spl pi/, and the third-synthesis of nonequidistant PAA with help of equidistant PAA with small shift of some radiation elements. The first and second methods have narrow bandwidth and cannot take full advantage of the diffraction lobe suppression in the visible zone. The second method requires complex computing expenditures. In this paper the construction of a nonequidistant PAA with the help of the aperture orthogonal polynomials method (AOP), which provide all the requirements, are discussed. The PAA wide bandwidth behavior, where the diffraction lobes does not appear, are considered.
