Abstract :
A sensor array processing algorithm for joint estimation of the directions of arrival (DOAs) and the corresponding angular velocities is presented, together with the Cramer-Rao bound (CRB) of the problem. An embedded movement model circumvents the problems of biased estimates or high measurement rates that occur when conventional DOA estimation algorithms are applied to moving targets.<>
