Abstract :
A new 2-D eigenstructure approach using the direction-of-arrival (DOA) matrix method and the ESPRIT method deals with the estimation of the DOA for multiple narrowband sources. Unlike the ESPRIT method, the former estimates the 2-D directions from both nonzero eigenvalues and corresponding eigenvectors of a DOA matrix. The relation between them is theoretically analyzed. It is shown that the ESPRIT method can be regarded as a special case of the DOA matrix method and that the DOA matrix method can give more generalized and more perfect results
