摘要

本文研究了基于TDOA的声定位方法的性能。采用泰勒级数展开法推导了该算法的统计源定位误差。通过仿真验证了时延估计误差和传感器节点数对定位误差的影响。此外，我们还研究了声源和传感器节点相对位置的影响。在理论和仿真结果的指导下，提出了一种实用的分布式声传感器网络设计方法。

A practical approach for acoustic sensor network design based on performance analysis of TDOA localization method

In this paper the performance of the acoustic localization method based on TDOA is studied. The statistical source localization error of this algorithm is derived using Taylor-series expansion method. Compared with the theoretical presentation, the impacts of the time delay estimation error and the sensor node number on the localization error are demonstrated by several simulations. Besides, we study the influence of the relative position of the acoustic source and the sensor nodes. Guided by the theoretical and simulated results, a practical approach for distributed acoustic sensor network design is proposed.
