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.
