Direction-of-Arrival Estimation Using the Rank-Revealing URV Decomposition
抄録
Appeared in Proceedings of ACASSP-91.
An algorithm for updating the null space of a matrix is described.
The algorithm is based on a new decomposition, called the URV
decomposition, which can be updated in $O(N^2)$ and serves as an
intermediary between the QR decomposition and the singular value
decomposition. The URV decomposition is applied to a high-resolution
direction of arrival problem based on the MUSIC algorithm. A virtue
of the updating algorithm is the running estimate of rank.
