| 摘 要： | 利用时频分辨率可调的广义S变换方法压制面波,将时间域地震信号变换到时频域,在时频域确定干扰区域,利用时频滤波器压制面波,再变换回时间域,其结果是得到滤掉面波的地震信号.处理结果表明,广义S变换在时频域进行压制面波方法可以达到分频分时准确衰减面波的目的.

| Abstract: | The paper shows a surface wave suppression method using generalized S-Transform whose time-frequency resolution can be adjustable.The method transforms seismic signal from time domain to time-frequency domain, and determines the interference regions in time-frequency domain.After eliminated surface wave with time-frequency filter, it is back to time domain to attain seismic sig nal and cut down surface wave.The results show that GST suppresses surface wave in time-fre quency domain with frequency dividing a... |
