摘要：

In this article, an extended particle swarm optimization (EPSO) algorithm is proposed for designing conformal phased arrays. On the basis of traditional particle swarm optimization (PSO), novel velocity updating mechanism, new exceeding boundary control operator, and global best perturbation are introduced in EPSO to overcome the drawbacks of PSO. To validate the efficiency of the proposed algorithm, both the classical test functions and the scenarios concerning a 1 x 9-element cylindrical conformal phased array and a 3 x 9(27)-element cylindrical conformal array with flat-top shaped-beam pattern are presented. Simulation results show that the proposed method is superior to genetic algorithm (G.A) and PSO when applied to both the classical test Functions and the practical problems of conformal antenna array synthesis.
