Abstract: Particle swarm optimization (PSO) procedure has been applied to find out a compensation for degraded pattern of a failed antenna array by amplitude only perturbation of few of the unfailed elements. The optimization technique finds the optimum amplitude levels of some of the unfailed elements in the array, so that the compensated pattern will match with the pattern of the original array, though not perfectly, but up to a satisfactory level. The reason for applying PSO is that it is simple to code and has small computational cost as compared to other soft-computing techniques. The developed formulation is tested for a 16-element linear broadside array. © 2008 IEEE.
