Abstract

Abstract

Under the condition of spatial subsampling, with flexible definition of fourth-order cumulant matrix of L-shaped array antennas output, utilizing the blind Gaussian and aperture extension properties of high-order cumulant, the estimation of frequency and two-dimensional(2D) Angles Of Arrivals (AOAs) are separated from the estimation of polarization of spatial non-Gaussian broad-band signals. An algorithm based on fourth-order cumulant ESPRIT and integral search is proposed to jointly estimate the parameters in multi-signal and arbitrary Gaussian noise environment. The array antennas are consisted of crossed dipoles that are parallel to the coordinate axes. Numerical simulation results verify the feasibility of this method.
