摘要：
A method for selecting a signal arrival for determining an accurate position of seismic equipment includes the steps of transmitting a signal from a pinger; predicting a direct arrival and a reflected arrival of the signal at a receiver, wherein each arrival is the time between the transmission of the signal to reception of the signal; measuring arrivals of the signal at the receiver; selecting the measured signal arrival that is similar to the predicted direct arrival as a preliminary signal arrival; defining a confidence interval for the actual direct arrival of the signal based on the predicted direct arrival and the predicted reflected arrival; and finalizing the signal arrival, wherein the selected preliminary signal arrival is the finalized signal arrival if it is within the confidence interval.
