摘要：

The performance of conventional direction of arrival (DOA) method is greatly affected by the uncertainty of wave velocity in underwater environment. To solve this problem, an acoustic velocity-independent method is proposed to estimate the underwater DOA using two arbitrary intersecting uniform linear arrays in this study. By introducing the additional array compared to the conventional DOA methods, the proposed algorithm can make its performance independent of the acoustic velocity through the geometric relationship between those two arrays. The simulation results demonstrate that the proposed method is more accurate and robust than other methods in an unknown sound velocity. © 2020, Posts and Telecom Press Co Ltd. All rights reserved.
