Design of steerable non-uniform linear array geometry for side-lobe reduction

In this paper, we present a pattern synthesis method of non-uniform linear array antennas for simultaneous reduction of the side-lobe level and pattern distortion during beam steering. To achieve these too requirements, the positions of linear array elements are adjusted using the Gauss-Newton method. It is shown that the proposed method can significantly reduce pattern distortion as well as the side-lobe level, although the beam direction is scanned. (C) 2003 Wiley Periodicals. Inc.
