Scientific paper

A simple two-dimensional technique for frequency-wavenumber estimation is presented which is a direct extension of a previously proposed one-dimensional frequency estimation technique. The proposed method is computationally efficient and is shown to be superior to the two-dimensional Fourier transform method in resolving signals closely spaced in frequency and wavenumber.
