A vector-hydrophone may form azimuth-elevation spatial beams that are invariant with respect to the sources' frequencies, bandwidths and radial locations (i.e., in near field as opposed to the far field). This paper adopts a multiple-forgetting-factor recursive-least-squares (RLS) adaptive algorithm to a single vector-hydrophone for source tracking, without needing any prior knowledge of the source power and/or the noise powers.}, keywords={Multiple-Forgetting-Factor;RLS adaptive algorithm;recursive-least-squares;source tracking;underwater acoustics;vector-hydrophone technique;hydrophones;least squares approximations;maximum likelihood estimation;target tracking;underwater sound;}, doi={10.1109/OCEANSAP.2006.4393830}, ISSN={},}
