Comparison between deterministic and stochastic methods for the synthesis of aperiodic arrays

The optimization problem addressed in this paper is that of minimizing the maximum sidelobe level of linear aperiodic antenna arrays radiating a pencil beam directed at broadside and having an assigned beamwidth and (eventually) desired nulls. A uniform amplitude distribution is assumed for the array elements. A deterministic approach is proposed, and its performance is compared with that of a stochastic method of recent literature.
