© 2016 Sinopec Geophysical Research Institute. Ground roll (GR) is a coherent noise phenomenon with high-amplitude and low-frequency patterns that conceal reflections. To create a correct velocity model, especially from medium to great depth, attenuation of the GR is unavoidable. To carry out attenu...
