Abstract

Inversion formulas are presented for determining the two-point spatial correlation function of the dielectric susceptibility of a quasi-homogeneous¹ random medium. The method requires that the medium be illuminated by plane-wave pulses and that the time resolved intensity profile of the scattered field in the far zone be known for all directions of incidence and all directions of scattering. The solution yields expressions for both constituent factors of the two-point spatial correlation function of the medium, namely the strength of the dielectric susceptibility and its degree of spatial correlation. We illustrate our analysis by some examples.
