Design of thinned arrays using Particle Swarm Optimization with differentially perturbed velocity

A hybridized optimization technique called particle swarm optimization with differentially perturbed velocity, is employed to two different types of thinned antenna array design problems and the performance is compared with that of particle swarm optimization and differential evolution. Two objectives to be reduced are the side lobe level in principal planes and the number of active elements. In the first case, thinning of a linear antenna array of 100 isotropic elements is considered. In the second case, thinning of a planar antenna array of 10×10 elements is considered.
