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).
