摘    要:为提高目前炮兵定位以及靶场试验弹丸落点检查精度,提出一种基于五元十字阵的双基阵定位模型.分析五元十字阵中测距、阵元间距对定位精度的影响,介绍利用声传感器阵列的被动声定位方法,利用三角交会法对目标进行定位并仿真分析.仿真结果表明:基于五元十字阵的双基阵比单基阵的测距相对误差小,能够有效提高定位精度,具有较好的工程应用价值.

关 键 词:被动声定位  五元十字阵  双基阵  弹丸落点

Abstract:For improving the accuracy of artillery and shooting range test the location of bomb falling point, the double array localization model based on five-element cross array. Analyze influence of ranging and array pitch of five-element cross array on positioning accuracy, introduce passive acoustic localization method of sonic transducer array, use triangle intersection to locate and carry out simulation analysis of object. The simulation results show that: the relative error of range using double array based on five-element cross array is smaller than the single one. The double array can improve the location accuracy, it has good engineering application value.
Keywords:passive acoustic localization  five-element cross array  double array  bomb falling point
