Methods to determine caracteru00ecsticas a ground training, speed of polarization of fast and slow shear wave in a formation of anisotropic earth.And the orientation of the fast and slow shear wave polarized in a formation of anisotropic earth.The patent discloses a technique of signal processing to determine the shear wave polarization of fast and slow, and its orientation.For acoustic waves in a formation of anisotropic earth.The method of signal processing decomposes waveforms received composed numerous times using many different angles of incidence.The decomposed signals are used to create the estimated source signals. The estimated source signals are compared in any way to obtain an objective function.Locations in a plot where the objective function reaches the minimum values are indicators of the acoustic speed of the fast and slow polarisation within the formation.
