【摘要】 设计了一种利用超宽带(UWB)技术的室内移动目标定位系统。通过在室内特定位置安装的基站和移动目标携带的标签,由改进的标准到达时间差(TDOA)定位算法,得到移动目标的实时位置信息,完成对室内移动目标的准确定位。采用Qt开发了一款上位机应用软件,可实时显示定位目标的位置及移动轨迹。最后搭建实验测试平台,对系统进行测试,将得到的位置信息与实际数据进行比对,结果表明系统整体通信稳定,满足定位需求。更多还原

【Abstract】 An indoor moving target positioning system using UWB(Ultra-wideband) technology was designed.Through the base sta-tion installed in a specific location in the room and the tag carried by the mobile object,the improved standard TDOA(Time Differ-ence of Arrival) positioning algorithm obtains the real-time location information of the moving target and completes the accurate po-sitioning of the indoor moving target.Qt was used to develop a PC application software that can display the position and movementtrajectory of the positioning target in real time.Finally,an experimental test platform was set up to test the system and the ob-tained location information was compared with the actual data.The result shows that the overall system communication is stable andmeets the positioning requirements.更多还原
