摘要
摘要:水下传感网络静默定位方法是一种可服务于多用户的免时钟同步定位算法，待定位节点全程无需发声，具有隐蔽性强和方便扩展等优点。该文提出了一种结合声线跟踪技术的水下传感网络节点静默定位方法，将高斯-牛顿法引入到水下网络节点静默定位中，解决了已有方法存在定位盲区的问题。鉴于水中声速分布不均的情况，将声线跟踪技术融入迭代过程，用以修正声线弯曲带来的定位误差。同时，针对实际应用过程中可能出现的信标节点阵型不佳的情况，采用了改进的Tikhonov正则化方法，根据目标函数变化情况反馈控制正则化参数，消除了雅可比矩阵不满秩对迭代过程的影响。通过仿真分析，验证了该文算法的有效性。

Abstract:The silent location algorithm for underwater sensor network is a time-synchronization free algorithm that can serve multiple users. No sound is needed of the target node in the whole process which make the algorithm secluded and extended. In this paper, a silent location algorithm for underwater sensor network based on ray-tracing technology is proposed. The problem of location blind area in the existing methods is solved by introducing the Gauss-Newton method into the algorithm proposed. In view of the uneven distribution of sound velocity in water, the ray-tracing technology is integrated into the iterative process to correct the positioning error caused by the bending of the sound ray. At the same time, considering the situation that the beacon node array may not be good in the practical application, an improved Tikhonov regularization method is adopted to control the regularization parameters according to the feedback of the iterative effect, which can compensate the influence of the singular Jacobian matrix on the objective function. The effectiveness of the proposed algorithm in this paper is verified by simulation analysis.
