Efficient DOA estimation by a specific SVD algorithm

In this paper an alternative algorithm for the Singular Value Decomposition (SVD) of the data matrix used for Direction-Of-Arrival (DOA) estimation is presented. The proposed algorithm transforms the data matrix into a bi-diagonal form by a procedure based on fast Givens rotations. This procedure is specifically tailored for DOA estimation and allows a certain computational saving with respect to the well known Golub-Kahan algorithm.<<ETX>>
