中文摘要：

SKS波分裂方法是研究地球内部各向异性的常用方法.随着地震资料数量的急剧增加,人工拾取并计算SKS波分裂需要耗费大量的时间和精力.本研究提出通过利用STA/LTA方法识别SKS波震相,利用时频分析确定滤波范围,并利用滑动时间窗时结果的稳定性选取SKS波时间窗,进而实现了SKS波分裂分析的自动化.运用该方法分析流动地震台站观测数据,并与人工计算SKS波分裂的结果进行对比,验证了该方法的正确性和可靠性.

英文摘要：

SKS wave splitting method is a common method to explore the anisotropy in the upper mantle. With the rapid development of modern seismic observation,it takes lots of time to do SKS wave splitting analysis on the enormous set of seismic data.Here,we developed a new software package to automatically analyze SKS wave splitting. Firstly,STA / LTA method is used to detect clear SKS wave,and time-frequency analysis is then conducted to determine the frequency band for filtering. Time window is the one in which the result changes least with the movement of the window.This new software package is applied to the seismic data from portable seismic stations, and the result is similar with those analyzing manually,verifying the reliability of the software package.
