Abstract
A novel data-supported optimization technique for maximum likelihood (ML) d irection-of-arrival estimation is proposed. The essence of our approach is to optimize the likelihood function at certain data-supported points obtain ed by a resampled root-MUSIC procedure. These points are shown to comprise a small but representative subset of all possible searching points and cont ain enough information for solving the ML problem.
