OSTI ID:7191687
This patent describes a method of geophysical exploration. It comprises: imparting seismic energy into the earth's subsurface formations with a source having a first time-varying polarization: recording a first set of seismic signals with seismic receivers having at least first and second linearly independent polarizations including at least one mode of shear wave propagation; and forming a weighted sum of the first set of seismic signals to ameliorate the effects of shear wave birefringence and to obtain principal time-series signals.
