| Zusammenfassung: | The invention provides a single-shot data signal-to-noise ratio determination method and device, and the method comprises the steps: carrying out the abnormal amplitude elimination of obtained single-shot data, and obtaining corrected single-shot data; according to the corrected single shot data, reflection signal data and noise data are obtained through separation; respectively processing the reflection signal data and the noise data to obtain amplitude spectrums, and calculating reflection signal data energy and noise data energy according to the obtained amplitude spectrums; and determiningthe signal-to-noise ratio of the single shot data according to the reflection signal data energy and the noise data energy. According to the method, the reflection signal data and the noise data areseparated, so the accuracy of the signal-to-noise ratio of the obtained single shot data is improved, the method is suitable for quantitative evaluation of the signal-to-noise ratio of the single shotdata in the seismic data a |
