空天地一体化传感器网络中的节点定位算法

Node Localization Algorithm for Space-Air-Ground Wireless Sensor Network

针对军用信息侦察的需求,提出了一种基于空天地一体化传感器网络的军用信息侦察系统。介绍了空天地一体化传感器网络的基本概念和网络结构,基于TOA和锚点的方向信息,提出了一种适于空天地一体化传感器网络的测距定位算法-TOA-D。仿真结果表明,该定位算法能够满足军用信息侦察系统对定位性能的需要。

In order to military reconnaissance and monitoring system problem, a new and feasible introduced the conception and structure of the Space-Air-Ground sensor networks（SAGSN）. Then presented a new localization algorithm of range-TOA-D based on the TOA and direction information of anchor for the application of the network. Simulations show that the TOA-D algorithm can satisfy the performance needs of military reconnaissance and monitoring system to localization.
