Abstract：By calculating cross-correlation functions between hydrophone data and Hilbert seismic trace sequence number, and geophone data and Hilbert seismic trace sequence number, we determine optimal phase matching factors. Then the optimal matching operator is directly calculated with the hydrophone data and phase matched geophone data. This method can quickly and reliably execute the matching processing of hydrophone data and geophone data. The proposed method is accurate and efficient. Real data applications demonstrate the effectiveness and practicability of the proposed method.
