Abstract
We present a tracking procedure based on the rank-revealing QR (RRQR) factorization and investigate its numerical properties by applying it to the direction-of-arrival problem. We address numerical issues raise d by the related work proposed earlier by Prasad et at, and we compare the performance of the proposed algorithm to that obtained using an E VD-based technique.
