Pencil Beamforming Based on Polynomial Approximation

This paper describes a straightforward method for the design of pencil-beam arrays with prescribed sidelobe level or mainlobe width. The method is based on the transform of a given array into the polynomial. Such an approach enables the application of the polynomial approximation in pencil beam synthesis. We applied it in the adjustment of Taylor-Kaiser arrays, in the design of arrays with minimum dynamic range ratio based on the transformed Gaussian windows, and in the combined array design incorporating rectangular and Gaussian window. The features of the method are illustrated with the design of linear arrays having low dynamic range ratio and high beam efficiency.
