| 英文摘要 | Full-waveform inversion (FWI) can supply accurate velocity model for seismic imaging and is becoming a very important technology in seismic exploration. The frequency domain modeling is the base of frequency domain FWI and can be used for each iteration. In this case, accurate and fast frequency domain modeling is very necessary. The traditional frequency domain modeling methods can only be used in square grid and the memory and computation requirements are huge. We present a high efficient and adaptable frequency domain modeling technique in this paper. |
