摘要 超宽带(Ultra-Wideband,UWB)技术能获得比现有无线定位技术更高的测距定位精度.本文主要讨论UWB定位技术的研究和应用,包括TOA/TDOA(Time/Time Difference of Arrival)等UWB定位方法、多径时延估计理论、非视距定位和协作式定位、多带OFDM(Orthogonal Frequency Division Multiplexing)定位和其他超宽带信号定位方式等方面,对其发展历程和现状进行了充分的叙述和分析,最后指出了仍存在的问题和值得进一步探讨的方向. Ultra-Wideband（UWB） has the ability of achieving the better ranging and localization precision than current wireless system.The research and application of UWB localization are studied on this paper,in which the main topics include the different UWB localization methods like TOA/TDOA（Time/Time Difference of Arrival）,multipath delay estimation theory,non-light-of-sight localization,cooperative localization,MB-OFDM（Orthogonal Frequency Division Multiplexing） and other ultra-wideband signals localization.Then its development and actuality are discussed in details.The existing problems and several future valuable research directions are summarized finally.
