Abstract :
An impulse radio (IR) ultra-wideband (UWB) over fiber sensor network for accurate localization based on optical time-division multiplexing (OTDM) is proposed and demonstrated. Neither clock synchronization nor parameter estimation is required in the proposed UWB sensor nodes. All complex signal processing is completed in the central station, which can greatly improve the localization accuracy and simplify the UWB sensor system. A proof-of-concept experiment is carried out. Two-dimension localization with centimeter-level spatial resolution is achieved.
