Open publisher page 7 citations

Abstract

A method of estimating direction of arrival which is based on Krylov subspace is proposed.Since Krylov subspace is equivalent to the signal subspace under some condition,by forming basis depended on incident angle and testing there equivalence,DOA can be obtained.The algorithm is done through multistage Weiner filtering.Simulation shows that the proposed method offers improvements in estimation performance for closely spaced signals.
