摘　　要：基于对标准遗传算法中收敛依赖于初始群体选择的困难所作的分析 ,提出交替使用两种遗传繁殖操作产生后代群体以摆脱收敛对初始群体选择的依赖 .对于超低副瓣线阵天线的方向图综合问题 ,建立了改进的遗传算法优化模型 .计算实例说明改进后的遗传算法其收敛不依赖于初始群体的选择 ,具有实际应用前景 .An analysis is made on the difficulty of genetic algorithms,in which the convergence is strongly dependent on the selection of initial population.A measure is proposed to alleviate the dependence of convergence on the initial population,in which two reproduction operations of different types are alternatively used in generating chromosoms.The model of improved genetic algorithm for the pattern synthesis of ultra low side lobe linear array antenna is established.A worked out example is given to demonstrate that the independence of convergence on the selection of initial population is realized in the improved genetic algorithm,showing its good application potentials.
