主 题：Array signal processing DOA estimation automatic pairing Rayleigh-Ritz theorem
摘 要：This paper presents a novel scheme for joint frequency and direction of arrival(DOA)estimation,that pairs frequencies and DOAs automatically without additional ***,when the property of the Kronecker product is used in the received array signal of the multiple-delay output model,the frequency-angle steering vector can be reconstructed as the product of the frequency steering vector and the angle steering *** frequency of the incoming signal is then obtained by searching for the minimal eigenvalue among the smallest eigenvalues that depend on the frequency parameters but are irrelevant to the ***,the DOA related to the selected frequency is acquired through some operations on the minimal eigenvector according to the Rayleigh–Ritz theorem,which realizes the natural pairing of frequencies and ***,the proposed method can not only distinguish multiple sources,but also effectively deal with other *** effectiveness and superiority of the proposed algorithm are further analyzed by simulations.
