Based on the analysis of auto correlation function, the notion of the distance between auto correlation function was quoted, and the characterization of the noise and the signal with noise were discussed by using the distance. Then, the method of auto adaptable endpoint detection of seismic signal based on auto correlated similarity was summed up. The steps of implementation and detemining of the thresholds were presented in detail. The experimental results that were compared with the methods based on artificial detecting show that this method has higher sensitivity even in a low signal with noise ratio circumstance.
