摘　　要：针对阵元位置误差影响DOA估计算法性能的问题,采用遗传算法寻找阵元的最佳位置进行校正。然后研究了在阵元数一定、放置范围可变和阵元放置范围一定、阵元个数可变的情况下,如何利用遗传算法对阵列进行优化。最后给出了计算机仿真结果。结果表明这种方法可以有效地对天线阵列进行误差校正及优化。Aimed at the effect of position errors on performance of DOA estimation algorithm, a method based on genetic algorithm is put forward. Also the case of certain number elements, the scope variable and the scope being certain but number variable how to make use of genetic algorithms to optimize the performance of array antenna is studied. At last, the simulating results are given which verified its correctness and usefulness.

关 键 词：遗传算法 阵列天线 DOA估计 优化
