A New Joint Estimation Method of DOA and Polarization Based on MP

A method is presented for the estimation of DOA, and polarization parameters of far-field sources based on four order cumulant. The method adopts ULA array, and every sensor consists of orthogonal dipole-pairs with the same coordinate axis direction, which measure the x-axis and y-axis electric-field components of the far-field signals. The method constructs three four-order cumulant matrixes by receiving polarized array data, and estimates the parameters of far-field according to the MP algorithm. The method does not require any spectral peak search and easy parameter pairing only, can be applied to additive Gaussian white noise environment. The performance of the proposed method is verified by computer simulations.
