Synthesis of amplitude taper beam steered linear array using Particle Swarm Optimization and Tschebyscheff polynomial

Abstract

In this paper, a novel method has been proposed to achieve reduced side lobe level (SLL) for beam steered linear array of isotropic elements. Tschebyscheff polynomial and Particle Swarm Optimization (PSO) algorithm has been used to develop the proposed method. In the proposed method search space for PSO has been defined using Tschebyscheff polynomial for an amplitude taper beam steered linear array. PSO with the information of where to search finds the optimum excitation amplitude of the beam steered linear array to achieve reduced SLL.
