Summary:
Most of conventional methods for Direction of Arrival(DOA) estimation are based on assumption that the number of elements is more than that of incoming wave. This paper proposes the technique calculating the covariance matrix from the first eigenvector to find a single incoming wave with the maximum field strength under the number of wave exceeding degree of freedom. This paper presents that the DOA estimation error for the wave with the maximum field strength is improved remarkably by the proposed method.
