1. An anisotropic elastic wave decoupling method applied to a seismic wave field, comprising:
determining a set of Thomsen parameters included in an anisotropic model based on a received to-be-decomposed wave field decomposition request, wherein, the to-be-decomposed wave field decomposition request comprises a to-be-decomposed wave field;
transforming the set of Thomsen parameters to obtain a set of initial elastic parameters;
performing S-wave and P-wave velocities separation processing for the set of initial elastic parameters to obtain a set of target P-wave elastic parameters and a set of target S-wave elastic parameters; and
substituting the set of target P-wave elastic parameters and the set of target S-wave elastic parameters into the anisotropic model to process the to-be-decomposed wave field and obtain a target P-wave matrix and a target S-wave matrix.
