摘要
建立了一种通用的适应度函数式,通过遗传算法对八元阵优化,逼近二项式分布和切比雪夫分布,验证了算法的正确性。通过对八元阵方向图不同目标的优化,说明该算法及适应度函数的设计对任意布阵天线方向图多目标优化的有效性。
The formulas of fitness are given in detail and the validity of procedure is verified by comparing the result of optimization using GA （Genetic Algorithm） with the binomial and Tchebyscheff distribution of an 8-element array. Then taking the 8-element array antenna for example, the effectiveness of multi-aim optimization of the radiation pattern of an array antenna whose elements are located randomly in the three-dimensional space using GA is proved.
