✦ Synopsis

Abstract

A genetic algorithm (GA) finds complex weights that yield low‐sidelobe levels for spherical arrays. The first example is a spherical–planar array with an initial high sidelobe of −13 dB, and which has an optimized pattern with a maximum sidelobe level of −27 dB. The second example is a spherical–circular array with an initial high sidelobe of −16 dB, and which has an optimized pattern with a maximum sidelobe level of −34 dB. © 2002 Wiley Periodicals, Inc.

Interruptions in the regular lattice of a phased array antenna can lead to elevated sidelobe levels in the resulting antenna pattern. A method for reducing the sidelobe level in such an array is presented, based on the use of a genetic algorithm that modifies the element weights in the array. Result
