Abstract
We consider here the problem of estimation ofDOA's of multiple wideband sources incident on a uniform lineararray (ULA) in the presence of spatially and temporally whiteGaussian noise (WGN). The approach presented here builds upon the IQML algorithm suggested by Bresler and Macovski forthe case of narrowband DOA estimation. It is shown that theconcept of ARMA model for the observed data vector for thenarrowband case can be generalized to model an appropriatelystacked, space-time data...Keywords
