声音无线传感器网络节点利用到达时间差( TDOA)原理进行声音目标定位，提出了一种正四棱锥形六元声音阵列定位模型。推导出了目标空间定位计算公式，应用广义互相关算法对时延进行估计。同时对模型误差进行了分析。最后通过仿真实验，可以对目标进行有效定位，定位误差小。

An acoustic localization wireless sensor network node uses the time difference of arrival( TDOA) theory to locate acoustic targets. It proposes a rectangular pyramid array with six sensors. The paper deduces the formulas of the target spatial orientation and uses Generalized Cross-Correlation algorithm to achieve time delay estimation. The paper analyzes the model error. Finally,through the simulation experiment,the target can be effectively positioning and the model error is small.
