For marine seismic acquisition, near-field hydrophone (NFH) are commonly used to monitor the status of source arrays. However, in recent years, with geophysical technology developed further and the innovation of geophysical equipment, the NFH used to record near-field data have gradually evolved into digital sensor with high precision, high sensitivity and high resolution. It has also been found that in the mode of multi-source acquisition, the near field data recorded by the source array can depict the seabed reflections under the background noise of the bubble direct arrivals. Therefore, a scheme for processing the near field data recorded by the NFH was proposed.
