摘要：This paper proposes a novel fast direction of arrival (DOA) estimation method for scenarios when uncorrelated and coherent signals exist simultaneously. First, using uniform transformation, we change complex matrix into real matrix, then, just by exploiting real propagator method (RPM), we can attain the uncorrelated signals DOA fastly. Second, based on new spatial difference technique, we can eliminate the effection of uncorrelated signals and make coherent signals become uncorrelated. Finally, utilizing RPM technique, coherent signals DOA can be estimated swiftly. Simulation results validate the performance improvement of the proposed algorithm.
