采用改进的遗传算法和改进差分进化算法结合的算法
but their sidelobe levels are high compared with the mainlobe leve1
So this paper aims at the problem of rarefying circular arrays antenna modules to minimize sidelobe levels as much as possible, applys the combination algorithm of the modified genetic algorithm(GA) and the modified differential evolutionary algorithm (DE), takes the angle subtraction as the chromosome gene, and then carries on arranging the certain array size, the certain number of array element and the certain minimum element spacing sparse optimization arrays with the advantages of reduced search region and enhanced search efficiency
The simulation results show that the method may enhance the convergence rate and reduce the circular arrays sidelobe levels effectively
