摘要：
A new rotation structure formulation of the popular ESPRIT for the central direction-of-arrival (DOA) estimation technique is considered. The steering vector of coherently distributed source is expressed as Schur-Hadamard product composed of point source steering vector and a real matrix. And then the new rotation structure is deduced to exist. So the TLS-ESPRIT can be used to estimate the central DOA of Gaussian coherently distributed sources. The so-obtained DOA estimate does not depend on any assumption on angular signal intensity of the source and is hence robust to mismodeling. Simulations clearly demonstrate that the proposed method is not only effective, but also has better estimation accuracy.
