| 초록 | In usual different filter methods are selected according to the differences between effective signal and noise for increasing the signal-noise ratio.But for complication of seismic data,sometime the effective signal and noise have no clear difference in apparent velocity and frequency.For this problem a method using S transform to fulfill the time-frequency filtering is presented in this paper,and the advantage of S transform in time-frequency filtering is compared with other filter methods through example. |
