... this challenge, our attention turns to Full Waveform Inversion (FWI), a method renowned for its ability to generate high-resolution velocity models using full waveform information. Despite its merits, several challenges persist in effectively applying FWI to BRI, including (1) a low signal-tonoise ratio in data...
