the experimental result proves that the application of the random noise attenuation technique to vsp data processing obviously improves signal-noise ratio and first break pickup.
试验结果证实,将随机噪声衰减技术用于vsp资料处理,可以有效地提高信噪比,改善初至拾取的精度。
random noise attenuation technique developed in recent years is obviously effective on improving the signal-noise ratio of surface seismic stack section(or stack migration section).
