| Abstract: | In recent years more and more artificial sources are used to explore underground structures in the regional scale deep exploration.Usually,signals from artificial seismic source have low SNR(signal to noise ratio).Artificial source has a certain degree of repeatability among different shots.On the basis of this character,we use phase cross-correlation and phase weighted stack which can effectively improve the clarity of the signal to detect weak signal.The study shows that by use of dozens of kilograms of e... |
