F-k filtering is a 2-D data processing technique that is based on a relationship between two domains: a time-space (t-x) domain and its Fourier dual, an f-k domain. This technique filters coherent noise for wavefield separation to produce better quality data. In short, f-k filtering relies on signal and noise separation via the 2-D Fourier transform. The region in the f-k domain where noise is present is set to be zero and the signal region is set to be one. Then the filtered shot record is restored by the inverse Fourier transform.
