Method and device for measuring the influence of ship motion on marine seismic survey

摘要

This method includes: (a) correcting the receiver's motion seismic data; (b) associating the receiver's corrected seismic data (a) with the reference frequency sweep signal from which the source is used to make seismic waves; (c) The calculation is directly transformed by the f-k (second period per meter period) of the data (b) to obtain the f-k transformation data; (d) select a fixed immersion part from the f-k transformation data; (e) The fixed immersion rate reverse conversion F-K in the f-k transformer data is calculated to obtain the reverse conversion F-K data;(f) A correction filter suitable for reverse F-K transform data is calculated. In addition, the system includes: (I) a seismic measurement and processing system, including a processing unit and a storage unit, in addition to the correction of seismic data moved by the source; (II) a user input system collected from a (I).（3） A (I) coupling display device
