Two-dimensional Prony modeling and parameter estimation
Joseph J. Sacchini, William M. Steedly, Randolph L. Moses · IEEE Transactions on Signal Processing · 1993
A new method for estimating the two-dimensional (2D) exponential modes and amplitude coefficients in a Prony model is presented. This method involves two parts, each utilizing a 1D singular value decomposition-based technique, and is capable of locating frequencies anywhere in the 2D frequency plane. Simulations are shown which demonstrate the performance of the algorithm.>
