It is shown how the ESPRIT algorithm may be used to estimate two-dimensional signal directions and polarizations with a polarization-sensitive array. The ESPRIT algorithm is a signal subspace method, which achieves computational efficiency by exploiting the spatial invariance properties of the crossed dipole array. With the ESPRIT algorithm, two-dimensional direction and polarization estimates are computed directly. The ESPRIT algorithm does not require a search over a multidimensional parameter space, as the MUSIC algorithm does.<
