在充分研究了超宽带无线传输技术特性的基础上, 对超宽带无线定位的原理进行了探讨。首先详细介绍了超宽带测距和定位的原理, 对超宽带定位的精度进行了仿真分析。然后, 针对超宽带 Ad Hoc 网络实际应用中节点数目比较多的情况, 引入了节点的相关性来提高超宽带的定位精度, 并进行了仿真分析。仿真结果显示了此算法在网络节点 ...
We consider the problem of target localization by a
network of passive sensors. When an unknown target emits an
acoustic or a radio signal, its position can be localized with multiple
sensors using the time difference of arrival (TDOA) information.
In this paper, we consider the maximu ...
