In time-of-arrival (ToA) based UWB localization, the accuracy of ranging is presumed. Especially for line-of-sight (LoS) scenarios it is assumed that by estimating the delay for the first arrival path (assumed to be the LoS) the distance between the transmitter and receiver node can be derived.
Using measurement data, we analyze the accuracy of the ranging based on the strongest path and the first-arrival path, the latter of which is dependent on its detection technique. Moreover the influence of frequency bands and signal bandwidth on ranging accuracy is analyzed. This is performed for two allocated mandatory subbands for ranging according to IEEE802.15.4a2007. |
