Embodiment Construction
[0045] The surface wave separation and suppression method based on the basis tracking algorithm includes the following steps:
[0046] (1) Formation of Ricker atomic overcomplete atomic library:
[0047] In this embodiment, two-dimensional seismic records and seismic sub-sections (256×80, 256 representing the number of sampling points and 80 representing the number of traces) intercepted from the actual seismic section (3501×354) were synthesized, and the synthesized two-dimensional seismic records and seismic The time sampling interval of the sub-profiles is ΔT=2ms. For the synthesized two-dimensional seismic records, the atomic main frequency parameters can be set according to the prior values. For the intercepted seismic sub-sections, the Fourier transform is first performed on each seismic signal of the seismic sub-sections, and the results are displayed in a spectrogram middle, Figure 6 (a) shows the Fourier transform spectrum diagram of 80 seismic signals of the actua...
