We use constant velocity migration of Ground Penetrating Radar (GPR) sections over a predefined range of migration velocities for the validation of diffraction focusing, using local slopes distribution, with the scope to estimate a migration velocity model. We avoid the user dependent diffraction analysis to circumvent subjectivity and use overlapping x-t windows to retrieve diffraction focusing validation for the entire dataset. The estimated migration velocity is utilized as an attribute whose sensitivity in water variation saturation is tested as a complementary method to the Electrical Resistivity Tomography (ERT) method for the assessment of soil moisture.
