摘要
提出了一种基于排序的实数码遗传算法并用于阵列天线的方向图综合。该算法对简单遗传算法的编码方式、选择策略、交叉和变异操作进行了改进 ,使搜索效率有了很大的提高 ,有效地避免了早期收敛。在实例设计中体现出优良特性 ,获得了比有关文献更好的结果。
A real coded genetic algorithm based on sorting is presented and applied to synthesizing the array antenna pattern by controlling only the current amplitudes. This algorithm improves on encoding, selection, crossover and mutation operations of SGA. It enhances searching efficiency greatly, and avoids effectively premature convergence. Good property is present in practical designs, the results obtained are better than those reported in the literatures.
