| Abstract: | The wave field decomposition is an important basic work of the multi wave multicomponent data processing. By using of the characteristics of dynamics and movement of the seismic wave, the decomposition of multi wave shot records is realized by the variable velocity method in F K domain. The P P wave and P SV wave in the x z two component records can be decomposed by the method. Having processed the x z two component records of both the theoretic and physical models, the good decomposed P P wave and P SV wave records were obtained. |
