一种改进的二维ESPRIT算法

Abstract

Abstract:

When the 2-D ESPRIT algorithm is used to treat two-dimensional signals, there is a great deal of redundancy in the arrays. A new 2-D improved ESPRIT algorithm was proposed. This algorithm used the geometries characteristic of a double linear array to construct a mixed matix, and then the signal subspace was obtained via the singular value decomposition of the matix in the 2D-ESPRIT method. This method could estimate the signal with less work, and get good estimation results. It could estimate both coherent signals and non-coherent signals by the spatial smoothing method.

Key words: direction of arrival estimation, 2-D ESPRIT, singular value decomposition, coherent signal
