In this paper, we present a positioning and tracking method for UWB signals. By the low complexity array processing, the time of arrival (TOA) and direction of arrival (DOA) is estimated. A robust algorithm based on the extended H_¡Þ filter is presented to accurately estimate the target's real-time location and velocity. This method is effective to the no-Gaussian or biased system model and the unknown or not fully known observation errors statistical properties.
