本文提出了一种利用已经布置好的成本相对低廉的环境噪声传感器网络，实现针对远场单一声源的被动式定位方案。首先通过滤波算法滤去噪声，然后利用声音随距离的衰减估计出目标点与测量点的距离，列出方程组求解目标位置。通过对天津某机场传回的实时数据进行的模拟演算得出的飞机航迹信息，我们证明了算法的合理性和有效性，并根据其精度不高的问题，提出了算法可以改进的方向。

This paper presents a method using an ambient noise sensor network system with relativly low cost nodes to realize passive localization towards distant field single sound source.Firstly,the noise is filtered by the filtering algorithm,and the distance between the target point and the measuring point is estimated by the Sound’s attenuation.Solve the equation to work out the target’s position.With the course line information from the simulated caculation of the real-time data from an Airport in TianJin.We prove that the method is reasonable and effective as wel as propose the direction of improving the algorithm.
