摘　　要：阵元幅相误差以及阵元间互耦的存在会使大多数高分辨DOA估计算法的性能恶化或失效。因此,阵列误差的校正技术在实际工程应用中具有重要的意义。本文基于一种经典自校正算法进行仿真分析,针对较多文章在理论上分析说明此方法对于均匀线阵的局限性,本文主要考查在实际应用中,在一定条件下此方法同样适用于均匀线阵。Because array element gain-phase and mutual coupling will make the performance of most high resolving power DOA algorithms worse of invalid, the technology of gain-phrase errors calibration is very important in practice. A classical self-calibration algorithm is analyzed, which demonstrates that this algorithm also fitting for uniform linear array under some conditions, although some paper shows limits from the point of view of theory.
