Abstract :
Some problem that have to be avoided in wavefield continuation in the space-frequency domain are instability, inaccuracy, and poor steep-dip performance. The practical design in convolutional operators for one-way wavefield continuation in the space-frequency domain places constraints on the operator length and range of useful wavenumbers. These problems are inherent in the design of anti-aliased, finite-length continuation operators and their subsequent application in a recursive manner. The author discusses two major limiting factors anti-aliasing and aperture limiting
