| 摘 要： | 定位和跟踪在无线传感器网络中具有重要研究意义，它们直接影响无线传感器网络的应用和发展。本文在WSN随机分布特性和天线阵列几何结构约束的基础上，通过节点协同形成的虚拟天线阵列对WSN进行定位和目标跟踪，从而提出一种适于定位和跟踪的虚拟阵列节点选择方法。仿真结果和理论分析表明，在DOA估计算法性能满足要求时，该方法具有很强的可行性和优良的定位性能。

| Abstract: | Localization and tracking are very important for the application and the development of Wireless sensor network. In this paper, we would introduce a new dummy array node selection method which based on the random distributing of the WSN and the restricted geometry structure of the sensor array. It would fix and track the WSN by dummy sensor array which produced by the node cooperation. The simulation results show that the new method have good performance in the feasibility and the localization under the requirement of the capability. |
