Abstract 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.
