A numerical pattern synthesis algorithm for arbitrary arrays

In this paper, a numerical method for antenna array pattern synthesis is presented. By this method, the designer can efficiently verify mainlobe shaping, null steering and sidelobe levels. When a large number of interfering signals occurred at various angles throughout the sidelobe region, the sidelobes are controlled by an iterative method based on adaptive array theory. The values of the weighting function in the L/sub 2/ norm, interpreted as imaginary jammers, and are iterated to minimize exceedance of the desired sidelobe levels and minimize the absolute difference between desired and achieved mainlobe patterns. Simulation examples, including both nonuniform linear and planar arrays, are shown to illustrate the effective of this method.
