Abstract:: In this paper,based on the data collected from Hutubi,Xinjiang Airgun Experiment,we adopted a newly developed wavelet propagator method to measure travel time shift between two waveforms.In addition,we introduced the surface wave amplitude as a new parameter to monitor the change of subsurface velocity.The results show that the relative surface wave amplitude could be an effective parameter,which is less sensitive to abrupt changes of the airgun source energy. to monitor the temporal variations of the subsurface velocity structure.We also observed a positive correlation between relative amplitude ratios and travel time delay,indicating focusing/defocusing effects accompanied by changes in velocity structure.In conclusion,the amplitude of surface wave can also be used as a stable parameter to measure the change of surface velocity.
