Based on the principle of single side autofocusing to solve Marchenko equation from the inverse theory in physics, the hardly eliminated seismic internal multiple can be converted into signal. Data driven primaries and multiples image will be performed to provide reliable subsurface image, to extend the illumination of reflection for the target layers and to enhance the quality of the seismic image with the signal from the target layers under the shadow of strong overburden reflector. The research objectives include to develop the method one side autofocusing to solve Marchenko equation about description for primaries and multiples from multi scattering theory, to convert the internal multiple into signal for the macro model without need of details of velocity and density, to retrieve of Green function at image point by using decomposition of up-going and down-going wavefields from recorded seismic data on the surface, and to perform seismic imaging with primaries and internal multiples and to be confirmed by the imaging process for numerical data and real data with rich internal multiples from both land and marine survey.
