Abstract:

We consider a randomly laminar structure of constant width and investigate the scattering of scalar waves for active remote sensing and radiometric purposes. The approach is based on analytic wave theory involving the expansion of-the field in Wiener-Hermite functionals, which are statistically orthogonal. A hierarchy of approximations is established and shown to represent in each order a partial summation of perturbation theory terms. The average field as well as the incoherently scattered field are determined, yielding the emissivity and transmissivity of the randomly laminar medium. The special case of small correlation length is examined in detail and proved to fulfill the energy conservation requirement.
