摘　　要：针对现有水下磁目标定位系统阵列结构复杂且数据冗余的问题,提出一种能够自矫正的新型简易空间直角四面体结构系统设计方法。建立磁目标定位算法,确定空间直角四面体阵列机构,仿真分析基线距离、信噪比以及定位距离对系统定位精度的影响,确定系统最优参数,并进行实验验证。实验结果表明:在百米距离内系统定位误差均值不超过1.5m,误差自校正后系统定位精度提高一倍,该系统在我军战略反潜、远洋侦察等方面具有较高的工程应用价值。Aiming at the disadvantages of complex structure and data redundancy of the existing underwater magnetic target positioning system,a novel simple space right-angled tetrahedral structure system design method which can self-correct is proposed. Magnetic target positioning algorithm is set up,compare and analyze the structural characteristics of different systems,verify the structure of the mechanism that with right-angle tetrahedron array in space,simulate and analyze the influence of baseline’s distance,signal-to-noise ratio and positioning distance on the positioning accuracy of the system to determine the optimal optimize the parameters,and verify the positioning accuracy of the system. The experimental results show that: the average positioning error of the system does not exceed 1. 5 m within a distance of 100 m,and the positioning accuracy of the system is doubled after the error self-correction. The system has high engineering applied value in our military’s strategic anti-submarine and ocean reconnaissance.
