Abstract:: Use the hierarchical clustering method in clustering analysis and waveform cross-correlation technique to study the uniformity of large volum arigun seismic source in Hutubi,Xinjiang.The signal is analyzed by the condition of the correlation coefficient that is greater than 0.95,and the corresponding similarity distance that is 0.05.The 3124 shots of Hutubi airgun seismic source between 2015 and 2016 is divide into two clusters.The repeatability analysis of several reasons of airgun source signal is discussed.Our final conclusion is the signal fluctuation is due to the different pressure caused by the airgun excitation.We propose to solve this problem by controlling the excitation pressure.
