Linear array synthesis using Schelkunoff polynomial method and particle swarm optimization

Particle Swarm Optimization (PSO) Algorithm with the Schelkunoff polynomial method (SPM) is used to synthesize the linear array. The problem of interference suppression in antenna array is done by Schelkunoff polynomial method. After that PSO algorithm is used to the control the side lobe level (SLL) reduction of the array pattern. It has been demonstrated that the complexity of the optimization problem is reduced by this technique. The simulated results shows proper null placement, reduction in SLL and beamforming capability.
