Abstract

Summary

Arrival time picking is useful in both active and passive seismic processing problems. Many current time picking methods suffer the problem of high false picking rate under low SNR cases. The random noise add wrong picking points that are far from the true moveout curves. In this study, we propose a new automatic arrival time picking method based on RANSAC curve fitting algorithm. Synthetic example indicates that the propose method is robust against high noise and can be used in multiple events scenario.
