Abstract:: In order to eliminate the influence of small seismic events and strong noise for the stacking effect of airgun signal,we propose a new method based on noise characteristics—Root Mean Square(RMS)screening method.It chooses the signal noise level as screeing criteria to remove the strong noise signal and is embedded in the automatic processing of massive airgun data.Practical application results show that the results of RMS screened linear and time-frequency domain phase weighted stacking are better than that of the conventional linear and phase weighted stacking method.Thereby it can increase the distance stations of weak signal detection effect and is of great significance to a series of subsequent researches on airgun signals.
