Abstract :
Steep seismic events are often aliased due to spatial undersampling of wave fields creating different kinds of coherent noises and corrupting the migration process, O. Yilmaz (1987). To avoid the expensive costs of high-resolution spatial sampling, seismic traces are interpolated. A novel spatial interpolation algorithm, based on a narrowband multichannel model, is considered
