Abstract：A blind 2D DOA estimation algorithm for cylindrical conformal array antenna with respect to po-larization is proposed by utilizing the characteristics of the singly curved surface of cylindrical carrier based on typical space DOA estimation theory.The algorithm is used to estimate direction of source exactly with-out knowing the source polarization and the element pattern.Meanwhile,the method can simplify the esti-mation without parameters pairing.The new algorithm can be implemented j ust by using a one-dimen-sional search and solution of equation.The first simulation estimates the performance of pitch and azimuth angle in the case of different SNR and the same snapshots by using Monte?Carlo statistical experiment.The second simulation utilizes the pattern of list to reveal the estimation result of pitch angle,and compares the influence on the estimation of azimuth angle by equation (32)and (33)algorithm in the case of the same SNR and different snapshots.The two simulations demonstrate that the effectiveness of the proposed method is verified.
