Abstract

In order to study on real-time tracking the seabed reflection in sub-bottom profile data acquisition, the two improved algorithms were discussed: energy ratio based on amplitude information and cross-correlation based on phase information, and the best window of energy ratio and the model trace of cross-correlation were especially studied. Because of the different advantages of the two improved algorithms, we should be agile when making the choice between them. The algorithms mentioned in the article are superior to most of these applied in foreign commercial software, and could be widely used in actual survey.

Key words
