METHOD AND APPLICATION OF FIRST-BREAK POSITIONING IN DATUM NETWORK ADJUSTMENT
Huaishan Liu, Siyou Tong · Marine Geology & Quaternary Geology · 2004
Because of the variation of seawater depth and tide, the detector placed in the seafloor cannot be located in the designed position during seismic exploration in the paralic zone. Therefore, by means of preliminary wave positioning of datum network adjustment, the detector can have its secondary exact positioning. At the same time, preliminary secondary positionings of wave and acoustic wave are compared and analyzed. Good effect has been obtained by the application of preliminary wave positioning of datum network adjustment during the high-precision seismic exploration in paralic zone KD-1.
