| 摘 要： | 针对目前超宽带室内定位技术至少需要4个接收器直接接收来自发射端信号的情况,利用超宽带高时间分辨率能力和室内环境中宽大平坦的反射物特征,提出了只用3个接收机的到达时间差(TDOA)三维定位方法.该方法利用多径延迟和发射物位置的信息进行定位.实验结果表明,本定位方法比传统的假设高度TDOA的方法测量精确.

| Abstract: | Aiming at the situation that four or more receivers of ultra-wideband(UWB) positioning technology are needed to directly receive signals from transmitting terminal.Positioning method for only three receivers with TDOA was proposed using high time resolution of UWB signals and character of big flat reflective surfaces in the environment to estimate the 3D position.This method can position applying of the information of multipath delay and reflector position.The experiment results showed that this method could determine the transmitter’s position with better accuracy than the conventional assumed height TDOA method. |
