چکیده
Abstract In this paper, Synthesis of sum patterns to generate narrow beams with individual heights of sidelobes which can be adjusted to any arbitrary specification using particle swarm optimization (PSO) is presented. The array design is first formulated as an optimization problem with the goal of reducing first two sidelobes to -50dB and by reducing the remaining sidelobes to -40dB. The objective of the PSO algorithm is to determine the optimized set of amplitude excitation coefficients to obtain the desired pattern. Using these optimized amplitude distributions, pattern are numerically computed for small and large arrays and are presented in θ domain.
