Approach for direction of arrival estimation based on 1-dimensional searching in the presence of mutual coupling
阵元间互耦条件下一维波达方向估计方法

By using 1-dimensional DOA searching rather than resort to multidimensional parametric searching, an algorithm for DOA estimation in the presence of mutual coupling is got. A necessary condition for identifiability is proposed. The ambiguous peaks appeared in certain cases must be eliminated. Detailed analysis of ambiguous problem is presented and is illuminated by numerical examples.
