摘　　要：提出了一种改进的适应度函数确定方法,算法采用易操作的二进制编码。通过改变适应度函数中的待定参数,有效提高了搜索效率。采用遗传算法对基站天线的方向图赋形,其结果优于同种条件下用Woodward法得到的结果。结合工程实践,考察了本文遗传算法的解的稳定性。An improved method of defining fitness function is presented. Higher efficiency of searching can be achieved by setting undetermined parameter of fitness function. One shaped-beam array antenna is designed using genetic algorithm, the result is better than Woodward. The stability of the answer to GA is checked for engineering practice. The results of this paper are important either for engineering and theory.
