摘　　要：定向精度是被动声纳系统的重要技术指标。建立六元阵模型,从理论上推导方位角、俯仰角及距离的误差公式。针对这种阵列的误差进行分析与仿真,最后,从仿真结果来分析该模型的定位性能。Precision of bearing estimation is important in sonar systems. In this paper, a model of six elements array is presented,a formula of azimuth, pitch and distance error estimation is derived theoretically. Simulation and analysis of the location error of an acoustic detection array commonly used are given. At last, the localization performance of this model is analyzed according to the simulation result.
