%X Based on the localization properties of wavefield decomposition and propagation in the Gabor-Daubechies beamlet (G-D beamlet) domain, a new method for construction of local scattering matrix is proposed in this study. Local scattering matrices from different acquisition systems for simple layered models are constructed and analyzed. The results indicate that the real scattering (or reflection) features of the local structure can be well approximated by the local scattering matrices if reasonable acquisition configurations are employed for data collection. The angle-dependent reflection coefficients for various velocity contrast cases, the space location and the dip angle of the interfaces are also estimated through detailed investigation on the local scattering matrices, which further demonstrates the great potential application of local scattering matrices to fine structure studies.
