Title: SYSTEMS AND METHODS FOR FAR FIELD SIGNATURE RECONSTRUCTION USING DATA FROM NEAR FIELD, MID FIELD, AND SURFACE FIELD SENSORS
Abstract:
A system and method for reconstructing a far field signature with data fusion from near field, mid field, and surface field hydrophone recordings is disclosed. The method includes receiving a first trace from a first sensor (e.g., hydrophone) and a second trace from a second sensor located in a different field from the first sensor. The method also includes receiving position information for the first and second sensors. The method further includes reconstructing a far field signature of the seismic signal based on the first trace, the second trace, and the position information.
