Data-driven clock drift adjustment
30 Mar 21
A method can include receiving seismic data acquired by a sensor unit responsive to emission of seismic energy in a frequency sweep of a duration having a duration time; correlating the seismic data and individual portions of the frequency sweep that correspond to individual time windows to generate individual sets of correlated seismic data; for a common event, identifying a corresponding event time in each of the individual sets of correlated seismic data; and determining a clock drift time based at least in part on the event times.
