| 摘 要： | 在基于距离的定位算法的基础上,提出基于超宽带（UWB）通信技术的TOA（Time Of Arrival）测距方法。UWB信号具有隐蔽性好、穿透能力强、定位精度高以及功耗低等特点,但在节点定位应用中,UWB直达信号难以精确检测。本文提出通过对首次到达信号时间和最强信号时间进行加权来得到直达信号到达时间,并采用模糊逻辑技术计算加权系数。实际数据仿真试验表明,基于UWB的定位技术可极大地提高定位精度。

| Abstract: | Using range-based localization methods,this paper raises a ranging method of TOA(Time of Arrival)based on ultra-wideband(UWB)communication technology.UWB signal has many beneficial characteristics such as good confidentiality,strong penetrating ability,high positioning accuracy and low power consumption.However,in the application of node localization,UWB direct signal is difficult to detect accurately.In this paper,the first signal arrival time and the strongest amplitude signal arrival time are weighted to... |
