Backscattering coefficients of a half‐space anisotropic random medium by the multiple‐scattering theory

Abstract: This paper is intended to study the electromagnetic wave scattering from a half‐space anisotropic random medium. The ladder‐approximated Bethe‐Salpeter equation in conjunction with the nonlinearly approximated Dyson equation is used to derive the modified radiative transfer (MRT) equations for wave propagation in the half‐space random medium. The MRT equations are solved under a first‐order approximation. Backscattering coefficients are calculated and are compared with those obtained using the Born approximati… Show more

“…This is because depolarized backscatter is essentially a second-order phenomenon in "isotropic" random medium. We also point out that depolarized backscattering is a first-order phenomenon in "anisotropic" random medium [Lee and Mudaliar, 1988]. In practical applications such as remote sensing, depolarized backscatter is very important because of its ability to discriminate between targets.…”

“…The simplest one is the first-order approximation. Lee and Mudaliar [1988] and Mudaliar and Lee [1990] have used this approximation to obtain analytic solutions for scattering coefficients of a half-space anisotropic random medium which in spite of the simplicity of this approximation lend considerable physical insight into the various scattering processes involved. The usual P.., •2 Region 2 rationale for this approximation is that if the medium is not too strongly scattering, then this approximation is a fairly good one.…”

“…O and P are scattering phase matrices for the coherent and incoherent intensities, respectively. The extinction matrices are given in (23) of Lee and Mudaliar [1988] and the expressions for Q and P can be found in the work by Lee and Kong [1988]. Here and henceforth we will refer to Lee and Mudaliar [1988] as…”

“…When the medium has strong fluctuations, perturbation methods are no longer valid. Dyson's equation for the coherent field [34] is exact in principle, but various approximate methods [34][35][36][37][38][39] are required to obtain a solution .…”
