Abstract :
Simultaneous frequency and wavenumber estimation using two-dimensional (2-D) linear prediction on a space-time data array is investigated. The method used is a direct extension of our previously presented one-dimensional (1-D) frequency estimation technique. It is relatively simple computationally and is superior to the 2-D Fourier transform method in resolving signals closely spaced in frequency and wavenumber.
