Abstract EN
A blind direction-of-arrival (DOA) estimation algorithm based on the estimation of signal parameters via rotational invariance techniques (ESPRIT) is proposed for a uniform circular array (UCA) when strong electromagnetic mutual coupling is present.
First, an updated UCA model with mutual coupling in a discrete Fourier transform (DFT) beam space is deduced, and the new manifold matrix is equal to the product of a centrosymmetric diagonal matrix and a Vandermonde-structure matrix.
Then we carry out blind DOA estimation through a modified ESPRIT method, thus avoiding the need for spatial angular searching.
In addition, two mutual coupling parameter estimation methods are presented after the DOAs have been estimated.
Simulation results show that the new algorithm is reliable and effective especially for closely spaced signals.
