| Abstract: | The low frequency component in acquired data from the marine seismic curvey is seriously interfered by the ambient noise frequently How to reduce the affection from the ambient noise to get more effective low frequency component from seismic data In this paper, the authors analyze the low frequency response of seismic system, get some relationship between the low frequency seismic system and the ambient noise, and present a better method to reduce the ambient noise It' s a good reference for the marine seismic fidle operation |
