摘要

摘要: 在诸多水中目标定位的方法中, 相对于纯方位目标定位与跟踪算法计算量大、实时性差、定位和估计精度不高的不足, 多基阵联合定位系统具有较强的抗干扰能力和生存能力。基于此, 文中提出了一种适用于水声网络的分布式基阵联合定位方法, 分别给出了Jacobi迭代法、三角重心法和最小二乘法等算法的仿真计算模型, 比较分析了3种不同定位方法在不同基阵数和分布态势下的定位仿真性能。仿真结果表明, 基于三基阵的Jacobi迭代法定位精度和收敛性要优于其他2种算法。最后, 根据应用情况提出了适合分布式基阵联合定位的阵型、基阵数以及阵间距等参数, 以期提高对目标的定位性能和网络生存能力, 为多基阵目标定位的工程应用提供参考。

Abstract: A multi-array joint localization system has the performances of strong anti-interference and survivability, compared with the bearing-only target localization and tracking algorithm, which needs a large amount of calculation and is of poor real-time performance and low accuracy of localization and estimation. In this paper, a distributed arrays based on joint localization algorithm is proposed for underwater acoustic network. Simulation models of the localization methods of Jacobi iteration, triangular center of gravity, least square method(LSM) are presented. The simulation performances of three localization methods for different array numbers and distribution situations are analyzed and compared. Simulation results show that the Jacobi iteration method with tri-array can achieve better positioning accuracy and convergence performance than the other two methods. Furthermore, the suitable parameters of array layout, array numbers, and distances among arrays for distributed arrays joint localization are proposed to improve the target localizing performance and the network survivability. This study may provides a reference for engineering application of multi-array target positioning.
