Method for velocity analysis using waveform inversion in Laplace domain for geophysical imaging

摘要

The system disclosed Laplace transform processor , the measured time domain wave field , velocity model , and Laplace damping constants and including , a processor calculates the zero frequency or zero frequency component in the vicinity of the time domain wave damping sheet and the Fourier transform , the time domain wave attenuated by the attenuation section attenuating the Laplace constant . According to this, it is able to obtain information about the velocity field wavelength deeper region .
