The high-frequency bathymetric side-scan sonar is affected by Gaussian color noise. To address this issue, a direction of arrival estimation method based on the fourth-order cumulant and amplitude-phase errors self-correction is proposed. First, the fourthorder cumulant of sonar echo signal is calculated to obtain the covariance matrix. Secondly, the weighted average algorithm is used to reduce the dimension, and obtain the construction matrix after dimension reduction. Thirdly, the amplitude and phase correction are accomplished by recovering the Toeplitz properties of the construction matrix. The phase linear fitting algorithm is added to further improve the correction effect. Finally, the Root-MUSIC algorithm is used to obtain the DOA estimation. Compared with the selfcorrection Root-MUSIC algorithm, simulation results show that mean square error of the proposed algorithm angle estimation is improved by about 0. 07°, which improves the problem that the estimation accuracy of the fourth-order cumulant algorithm decreases under the condition of the amplitude-phase errors of the array elements. Compared with the self-correcting Root-MUSIC algorithm, the sea test data analysis shows that the relative bathymetric accuracy of the algorithm in this article is improved by about 0. 03% ~ 0. 08% and the bathymetric accuracy standard of 0. 75% is satisfied within the horizontal distance of 90 m. Both simulation and sea trail data prove that the DOA estimation performance of the proposed algorithm is better than the traditional algorithm under the conditions of Gaussian color noise and array elements amplitude-phase error.
