ABSTRACT
Ultra wideband (UWB- Ultra Wideband) technology as a hot research field of wireless location in recent years, with high accuracy, low cost, plexity, high transmission rate, high concealment, etc., are widely used in various fields, such as military ultra wideband radar,daily monitoring etc.. In particular,ultra wideband technology is paid more attention to for its high accuracy performance fully demonstrated in the positioning technology advantage in the increasing demand of modern this thesis, ultra wideband system with high precision for the key to carry out the following work on the characteristic of ultra wideband electronic tag system.
The basic situation of UWB systems, investigation research main application fields at home and abroad, in-depth analysis of the working principle and structure of the system.
Start from the various positioning technology, analyse the advantages of UWB system in the positioning technology and key elements used in the field of ultra wideband in-depth study of the system, including the pulse selection,modulation technology,antenna technology are the next. In the pulse generation technology, design the pulse index on the actual location needs, simulate the technology of pulse pare the advantages and disadvantage
