INVERSION FROM FINITE OFFSET DATA AND THE SIMULTANEOUS RECONSTRUCTION OF THE VELOCITY AND DENSITY PROFILES

Recursive inversion algorithms are described which facilitate a direct inversion of a one-dimensional velocity distribution from finite offset data and the related simultaneous reconstruction of a two-parameter, say velocity-density, medium. The suggested procedures are based on an extended format of the WKBJ-Bremmer scattering model. The attained accuracy levels and the limitations are highlighted by computer simulations against synthetic data.
