研究目的
Investigating the effects of imperfect sampling on Marchenko imaging and introducing discrete representations to account for these effects.
研究成果
The discrete representations introduced in this study account for the effects of imperfect source sampling in Marchenko imaging, quantified by PSFs. These representations form the basis for modifying the Marchenko method to handle imperfectly sampled seismic field data, with ongoing research focusing on further development and application.
研究不足
The inversion of the upgoing focusing function may not always be stable due to its nature as a reflection response. Additionally, the method's performance may be affected by the limitations of the MDD method, especially at far offsets where amplitudes can be overestimated or underestimated.
