Correlation Transformation of Field Vibragram with the Account of Distorces of Phase Spectrum of Swip-signals
The original method of correlative transformation of vibrograms, which takes into account the distortion of reference signals in environment with frequency-dependent attenuation on the energy of elastic vibrations. The experimental material shows that the proposed method of calculating correlograms allows to significantly improve the quality of vibroseis materials. The possibility of calculating the attenuation decrement, which carries a significant amount of additional information on the structure and properties of the geological section, is also discussed.
