摘　　要：四元平面方阵是最简单的半空域无源定位传声器阵列,其定位精度受多种因素影响,其定位误差主要由时延估计误差引起,针对这种阵列的定位误差进行了分析与仿真,主要讨论了时延估计误差对定位精度的影响,最后从仿真结果看出该阵的测角精度较高,测距精度很差。Time delay localization is in common use in air acoustic detection. Simulation and analysis of the localization error of an air acoustic detection array commonly used are given, discussed are mainly the influence of time delay error on localization precision and some problems in the localization arithmetic.
