Abstract: Coherency technology is very important to fault analysis and construction interpretation. Traditional algorithm of coherence cube is too complex to run in PCs so the technological application of coherence cube is restricted. In this paper, two concepts, signal matching distance and wave similarity coefficient, are defined and their way of calculation and the relevant algorithm are presented. By means of experiments, compared with the traditional algorithm, |C1| algorithm, the two algorithms are similar in the ability of fault recognition. Meanwhile, the new algorithm is much faster. As a result, the new algorithm can improve the speed by 11 times.

Keywords: coherence cubes; visualisation; signal matching distance; wave similarity coefficient; fault recognition; fault analysis.
