Abstract：Based on simplified electromagnetic vector-sensor array, a new Dimension Reduction Quaternion MUSIC (DR-QMUSIC) algorithm is proposed. In this paper, the quaternion algebra is first introduced since the orthogonality of quaternion is suitable for describing the orthogonal structure of electromagnetic vector-sensor very well. Then, the quaternion model of simplified electromagnetic vector-sensor array is established, and the DOA of polarized signals is estimated by employing the DR-QMUSIC algorithm. Inserting the estimated DOA into the traditional V-MUSIC algorithm, the polarization parameters of polarized signals are estimated. Thus, four unknown parameters of polarized signals are obtained. The simulation experiments are given to validate the proposed algorithm.
