【摘要】：提出了一种改进引力搜索算法,通过引入遗传算法的变异算子,提高了引力搜索算法的局部搜索能力,解决了引力搜索算法在阵列天线赋形波束应用时的实现方法和早熟收敛问题。在阵元个数及阵元间距一定的情况下,对阵元激励的幅值和相位进行优化,使赋形波束达到设计要求。实验结果证明了该改进方法的可行性和有效性。
[Abstract]:An improved gravitational search algorithm is proposed. By introducing the mutation operator of the genetic algorithm, the local search ability of the gravitational search algorithm is improved. The problem of precocious convergence and the realization method of gravitational search algorithm in array antenna shape beam application are solved. When the number of array elements and the spacing of array elements are fixed, the amplitude and phase of the excitation are optimized to make the shaped beam meet the design requirements. The experimental results show that the improved method is feasible and effective.
