Detecting pedestrians in blind spots is a critical component of ensuring vehicle safety, especially in urban environments. This paper presents a pedestrian localization system utilizing a single ultra-wideband (UWB) anchor installed in a moving vehicle. The proposed system leverages UWB's robust ranging capabilities to estimate the position of a pedestrian carrying a UWB-enabled smartphone, even in Non-Line-of-Sight conditions. The focus is on analyzing the UWB ranging protocol performance when the anchor is in motion and how the position of pedestrians can be estimated in both two-ranging and three-ranging point scenarios. Experiments are conducted at various vehicle speeds and demonstrated the effectiveness of the approach.
