Shear-wave splitting is an important characteristic of anisotropic media�� Generally��when S or P-SV waves reach to the ground through anisotropic media��the seismic record received by x component and y component of three-component detector contains fast wave and slow wave simultaneously�� Separating fast wave and slow wave and then calculating the anisotropic parameters of media are an important step in multi-component data processing�� The authors introduce the Pearson correlation coefficients into multi-component seismic exploration and propose the Pearson correlation coefficients to detect the rotation angle and then separate the fast wave and slow wave�� Compared with the traditional cross-correlation method��the Pearson correlation coefficient method is better in accuracy�� noise immunity and computational efficiency��
