超宽带（UWB）信号适用于使用到达时间差（TDOA）或时延估计（TDE）技术进行定位测量。然而，由于天线元件、其他系统组件以及多径传播环境导致的脉冲失真，使得TDOA估计变得复杂。本文探讨了基于互相关的TDOA方法的使用，并结合一种新技术，将来自多个天线对的TDOA估计值进行组合，以构建发射机位置的估计。在消声室中进行了模拟植被和工业环境的实验。给出了这些测量的结果。
Ultra-wideband (UWB) signals lend themselves to localization measurements using time difference of arrival (TDOA), or time delay estimation (TDE), techniques. However, TDOA estimation is complicated by pulse distortion due to the antenna elements, other system components, and the multipath propagation environment. This paper explores the use of cross correlation based TDOA methods in conjunction with a novel technique for combining the TDOA estimates from multiple antenna pairs to build an estimate of the transmitter position. Experiments that simulate foliage and industrial environments were performed in an anechoic chamber. Results from these measurements are presented.
