Topic 13: Harmonic noise suppression and aliasing signal separation for vibroseis data

1. A joint special noise suppressing technology for vibroseis data after cross-correlation is proposed based on the characteristics of the two kinds of special noise, in which the harmonic noise is firstly suppressed by the predictive filtering method based on a feedback system, and then the surface response noise is suppressed by the frequency division method.

2. Different techniques are used for vibroseis aliasing data acquired from different acquisition methods.
