Abstract :
This paper provides a positioning and tracking method for UWB signal sources. The time of arrival (TOA) and direction of arrival (DOA) of UWB signal sources are estimated by the low complexity array signal processing. A robust tracking algorithm based on the extended H∞ filter is presented to estimate the moving targets location and velocity accurately. This method is effective to the no-Gaussian or biased system model and the unknown or not fully known observation errors statistical properties.
