摘要：

A new algorithm for estimating the frequencies of the two-dimensional (2-D) exponentials is presented. Via joint diagonalization of a set of matrices, the estimation of the automatically paired 2-D frequency parameters are obtained. Hence the proposed algorithm can avoid the computationally expensive 2-D parameters pairing procedure. Simulation results validate the high performance of the new algorithm.
