The effective removal of coherent noise from seismic data has become a problem of much concern. The authors used hybrid radon transform to separate linear noise from seismic section once for all, then eliminated multiple wave in radon domain using adaptive filtering technology and used the inverse hyperbolic radon transform to get the effective reflection seismic signal. Theoretical model and practical data test show that this technology is effective in multiple wave attenuation. Similar function was used to suppress the end effect and truncation effect. The actual calculation results is good and shows that hybrid radon transform can simplify noise suppressing of data processing.
