Abstract

An algorithm of Directions Of Arrival (DOA) estimation based on the state-space method is proposed to deal with the problem of estimating DOA of multiple source signals from a single observation vector of distributed array. Hankle matrixes are firstly constructed by using the single snapshot of every subarray element. Then low accuracy and unambiguous DOA estimations are obtained by the single subarray, while high accuracy and ambiguous DOA estimations are obtained by the distributed array. Finally, high accuracy and unambiguous DOA estimations are obtained by using automatic pairing decorrelating. This algorithm has no relations with the correlation signals and can fully take advantage of the large aperture to acquire high DOA estimation. Computer simulation results confirm the effectiveness of the proposed algorithm.

Key words： DOA estimation Distributed array Hankle matrix Decorrelating
