Abstract:

The concept of frequency wavenumber beamforming of a linear array of equispaced receivers is reviewed. The frequency wavenumber spectrum can be evaluated by using a two-dimensional Fast Fourier Transform and the properties of the resulting estimate of the frequency wavenumber spectrum are described. Particular attention is given to the distortion of the spectral power estimates due to leakage of negative frequency components. Author
