Direction of Arrival and the Rank-Revealing URV Decomposition [PDF]
, 1998 In many practical direction-of-arrival (DOA) problems the number of 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.
