Abstract A new polarization smoothing algorithm is proposed for the 2-D direction finding of coherent cyclostationary signals. By sufficiently utilizing the cyclostationarity and polarization diversity, the proposed method increases the number of coherent sources that can be estimated and has the signal-selectivity and noise-robustness, without impacting the aperture of the sensors array. All parameters match automatically in the estimation process. Simulations are presented to show the performance of the algorithm.
