Abstract
This paper investigates the estimation of parameters, including azimuth, elevation, polarization auxiliary angle and polarization phase difference of near-field sources in a polarimetric uniform linear array (P-ULA) with defective electromagnetic vector sensors. At the design stage, the cross-distribution dipole pairs are alternately placed in the xoy-plane and the yoz-plane, respectively. Specifically, the polarization auxiliary angle and phase difference as well as azimuth and elevation of the source are estimated based on the fourth-order cumulant (FOC) matrix in each subarray. Moreover, a decoupling method is developed to obtain the azimuth and elevation. Finally, the parameters pair matching is performed to eliminate the estimation errors. Simulation results are provided to verify the effectiveness of the proposed method for multi-dimensional parameters estimation.
