The use of quasiorthogonal sweeps for simultaneous sourcing in vibroseis survey

Simultaneous acquisition techniques allow obtaining greater volumes of data and sophisticate its recording geometry through the use of several sources. Depending on the method of seismic (vibrational or pulse), different methods of signals separation are used. In this study, we demonstrate some methods of constructing uncorrelated signals for vibroseis simultaneous acquisition, their application on the example of synthetic data and the removal of the cross-correlation noise on the synthetic seismogram with use of hyperbolic median filtering.
