| Ultra wideband (UWB-Ultra Wideband) technology as a hot research field of wirelesslocation in recent years, with high accuracy, low cost, low complexity, high transmission rate, highconcealment, etc., are widely used in various fields, such as military ultra widebandradar,daily monitoring etc.. In particular,ultra wideband technology is paid more attention to forits high accuracy performance fully demonstrated in the positioning technology advantage in theincreasing demand of modern positioning.In this thesis, ultra wideband system with highprecision for the key to carry out the following work on the characteristic of ultra widebandelectronic tag system.(1)The basic situation of UWB systems, investigation research main application fields at homeand abroad, in-depth analysis of the working principle and structure of the system.(2)Start from the various positioning technology, analyse the advantages of UWB system inthe positioning technology and key elements used in the field of ultra wideband positioning.Anin-depth study of the system, including the pulse selection,modulation technology,antennatechnology are the next. In the pulse generation technology, design the pulse index on theactual location needs, simulate the technology of pulse used,compare the advantages anddisadvantages of each method.(3)The software simulation of pulse generating circuit includes the main influence parameterson the results are used, as well as the research conditions, and determine the parameters of drawingboard for the experiment in order to test the accuracy of the simulation parameters,analyse theexisting problems in simulation and experiment. The general structure and principle diagram ofultra wideband electronic tag are finally designed. |
