通常情况下,海上测量的低于6～7Hz记录因信号噪音大而无法利用,但分析这些低频信号可以帮助我们在以后的采集中减少信号噪音。文中讨论了低频成分在盐下成像中的独特优势。
Oftentimes, measurements of less than 6 to 7 Hz at sea are not available due to large signal noise, but analyzing these low-frequency signals can help us reduce signal noise for later acquisitions. The article discusses the unique advantages of low-frequency components in sub-salient imaging.
