TY - RPRT T1 - Direction of Arrival and the Rank-Revealing URV Decomposition Y1 - 1998 A1 - Boman,E. C A1 - Griffen,M. F A1 - Stewart, G.W. KW - Technical Report AB - In many practical direction-of-arrival (DOA) problems the numberof sources and their directions from an antenna array do not remain stationary. Hence a practical DOA algorithm must be able to track changes with a minimal number of snapshots. In this paper we describe DOA algorithms, based on a new decomposition, that are not expensive to compute or difficult to update. The algorithms are compared with algorithms based on the singular value decomposition (SVD).
