到达时间差(Time Differenceof Arrival,TDOA)是一种利用到达时间差进行定位的方法又称为双曲线定位。TDOA算法并不是直接利用信号到达时间,而是利用多个基站接收到信号的时间差来确定移动目标的位置。因此与TOA相比并不需要加入专门的时间戳来进行时钟同步,定位精度相对有所提高。
Time Difference of Arrival (TDoA)Ultra Wide Band (UWB)Indoor location using radio frequency (RF) signals has been traditionally focused mainly on RSSI and fingerprint techniques, because methods based on time of arrival (ToA) or time difference of arrival (TDoA) were not suitable for measuring ...

time difference of arrivalThe recent interest in ultra-wideband (UWB) systems requires an accurate modelling of the radio channel characteristics. Among these, the fading properties of the UWB channel are of particular interest in the development of the air interface. This paper reports on an ...
Ultra wideband (UWB) is a good candidate for indoor positioning, thanks to its ability to resolve multipath and penetrate through walls. This study investigates the performance of UWB-based time difference of arrival (TDOA) positioning for indoor environment, where one or more blind nodes are to...
