A joint estimation algorithm of direction of arrival (DOA), frequency, and polarization, based on fourth-order cumulants and uniform circular array (UCA) of trimmed vector sensors is presented for narrowband non-Gaussian signals. The proposed approach, which is suitable for applications in arbitrary Gaussian noise environments, gives a closed-form representation of the estimated parameters, without...
On the basis of a uniform circular array of trimmed vector sensors, a novel cyclic ESPRIT-based approach is proposed for direction finding and polarization estimation of multipath cyclostationary signals. By exploiting the cyclostationarity and the polarization diversity of the signals, the proposed method improves the resolution power and offers comparable performance as the optimal methods likelihood...
