| Abstract: | Abstact In this paper,a novel Particle Swarm Optimization based on Linear Decreasing Weight Particle Swarm Optimization(LDW-PSO)is presented.In order to improve the optimization speed and convergence performance,neighborhood topologies,stagnation detection and global best perturbatio are adopted to build the novel algorithm.The simulation results show its high performance in the radiation antenna arrays pattern synthesis with multi-null and low side lobe restrictions. |
