Breakthrough Most Array Error Correction Techniques In view of the limitation of the scalar sensor array error model, a method to self-correct the array error of the electromagnetic field vector sensor is proposed. The proposed method is based on the vector sensor array model with azimuth dependence on the amplitude and phase error of the array element. The proposed algorithm can analyze the source orientation, polarization parameters and the corresponding array amplitude and phase error of a multi-source signal under any polarization state based on the idea of subspace, The proposed method is suitable for vector sensor arrays with arbitrary geometric structure. Simulation results show the effectiveness of the proposed algorithm.
