New high efficiency ESPRIT method on DOA estimate of coherent sources

ESPRIT algorithm is a common algorithm of high speed and high precision,but it didn't estimate coherent signal.Aiming at the bug,this paper proposed a new improved ESPRIT algorithm of DOA(direction of arrival) estimate of high efficiency and coherent source.Eigenvector corresponding to the maximum eigenvalue of the data correlation matrix could be arranged via method which was raised.It solved the following problem of routine ESPRIT algorithm:not estimating coherent signal.Meanwhile,compared with routine ESPRIT algorithm,it greatly simplified computable course.Computer simulator realization makes sure that it is DOA estimate algorithm of high efficiency,resolution and precision in estimating coherent signals,it provides new approach which ESPRIT algorithm of estimating coherent source has application on high resolving field of array signal.
