Signal processing in ocean bottom seismographs for refraction seismology

摘要

This communication presents some experimental results about the wavelet techniques applied to seismic signal processing. These techniques have been used to process seismic signal and now we'll applied these well know techniques to refraction seismology. Ocean Bottom Seismometer, OBS, represents the achievement of a joint work from different scientific and technological disciplines as electronics, mechanics, acoustics, communications, information technology, marine geophysics, etc. This easy to handle and sophisticated equipment allows to record useful active and passive seismicity information, as well as other wave front, with multiple applications to the marine environment research.
