| Description | Journal: Journal of Physics: Conference Series In array signal processing, direction of arrival estimation (DOA estimation) is a common and extremely important $method^{1}$. This paper is based on the existing DOA algorithm, and conducts deeper research. Firstly, compare three DOA estimation algorithms using simulation program. The experimental results prove that the MUSIC algorithm has the highest accuracy. Secondly, we analysis the basic theory of MUSIC algorithm, and then discusses the factors of affecting the estimation accuracy of MUSIC algorithm. Finally, in view of the shortcomings of the MUSIC algorithm for solving the problem of coherent sources, this paper improves the MUSIC algorithm, then proposes an improved algorithm, which is verified by simulation experiments. |
