摘要：
This paper considers the direction of arrival (DOA) estimation of quasi-stationary signals for arbitrarily spaced sensor array at unknown locations. We derive a close-form DOA estimation algorithm for arbitrarily spaced sensor array at unknown locations when exploiting an auxiliary sensor. Our algorithm illustrates better DOA estimation performance compared to the interpolated ESPRIT algorithm. Furthermore, our algorithm requires no spectral peak searching, and it is insensitive to the distributions of the sources. Numerical results demonstrate the validity of our algorithm.
