摘　　要：实际应用中天线阵列位置误差通常存在,导致超分辨参数估计算法性能急剧下降。本文通过分析阵列误差模型,在信号子空间迭代自校正方法的基础上利用遗传算法随机化搜索、全局寻优的特点,提出了一种基于遗传算法的阵列误差校正方法,并通过计算机仿真验证了该方法的性能。Since the array has unavoidable position errors in practice, the performance of the super-resolution parameters estimation algorithms would decrease badly. An array error correction method with the genetic algorithm has been proposed through error analysis in this paper. The method had made use of the random seeking and global optimization characteristics of the genetic algorithm based on the signal subspace iteration self-calibration. The simulation result was presented to show the feasibility and validity of the method proposed.
