Frequency Domain DOA Estimation and Tracking of UWB Signals

This paper deals with the problems of estimation of directon of arrivals (DOA) and tracking of the ultra-wideband (UWB) signals. The UWB pulse position modulation signals from the moving targets incident on antenna elements in the presence of white Gaussian noise, a frequency domain MUSIC algorithm is proposed to estimate the DOA of the multiple moving targets. A robust algorithm based on the extended H_∞ filter is presented to accurately estimate the target´s real-time location and velocity. The performance of this estimation of DOA and tracking strategy was also evaluated by the computer simulation.
