The Application of Circular Sparse Antenna Array Synthesis Based on Differential Mind Evolutionary Algorithm

Mind Evolutionary Algorithm (MEA) imitates the human mind evolution by using similartaxis and dissimilation operations,which overcomes the prematurity and improves searching efficiency. But the addition of naturally washed out temporary subpopulations is blind and random; the existing searching modes are easily to fall into local convergence.This paper proposed Differential Mind Evolutionary Algorithm (DMEA), which saved the excellent genes in the evolution and brought adequate diversity to the population by introducing the thought of difference into dissimilation operation.Then DMEA is used in the synthesis of circular sparse antenna arrays.The excellent results of computer simulation show the advantage of array antenna patterns synthesis using DMEA.
