The finitedifference compensation was applied to the wide angel correction of the elastic screen propagator, and the vector imaging condition was employed through projecting components in the direction of polarization. The information from the elastic wave field could be used efficiently, and the problem of inconsistent polarization of PSV in imaging was solved. Partial images from different sources could be stacked to generate a final image. The elastic screen propagator with wide angel correction and the vector imaging condition were tested with the model data, which proved the reliability of this method.
