An improved 2-D ESPRIT algorithm
Wei Ting · Journal of Shandong University · 2010
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.
