摘要：

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 raised by the related work proposed earlier by Prasad et at, and we compare the performance of the proposed algorithm to that obtained using an EVD-based technique.
