    • Using three independent observed parameters (i.e, the surface echo amplitude, the subsurface echo amplitude, and the delay time of the subsurface echo relative to the surface echo, we need to determine four independent parameters (i.e, dielectric constants of two subsurface layers, the loss tangent of the top layer, and the depth of the subsurface reflector, To solve this ill-posed problem, we inversely solve a Fresnel model of three media (i.e, vacuum and two subsurface layers) assuming normal incidence and a moderate value of 4 for the dielectric constant of the top layer
