- Abstract
Time reversal technique as an excellent channel equalization technologywhich can restrain multipath effectively to implementation time focusing and can improve the distribution of energy in space to implementation spatialfocusing.This paper aim to improve the shortcomings with poor accuracy of positioning,a large amount of calculation,sensitive to the environment for the existing location method indoor.what make full use of strongly time resolution and spatiotemporal focusing characteristics of TR in UWB.From the perspective ofcollection multipath energy,which brings together time reversal theory,UWB technology TOA to research the effect factor of obstacles in NLOS environment.This paper introduce ranging process of windowed time reversal in indoor environment.With a large number of ranging experiment are carried out,analysed the sources of measurement error in NLOS environment and compared its effects.Simulation results show that the influence of obstacles on ranging.From large to small in turn as the length,width and position which lay the foundation for the next node positioning.
