Abstract The Direction-Of-Arrival (DOA) tracking of coherent signals is researched based on polarization vector- sensor array. The decorrelative performance of a Single Snapshot Polarization Smoothing Algorithm (SSPSA), which is available for the fast estimation of DOA in multipath environment, is analyzed. The algorithm can improve the effective array aperture. Then a subspace tracking algorithm of coherent sources is presented based on iteration. The iterated algorithm has higher tracking speed and requires neither the eigen-decomposition into signal/noise subspace nor the inverse operation of matrix. Simulation results verify the effectiveness of the proposed algorithm.
