Polarimetric scattering from inhomogeneous random media under a pulse incidence

Polarimetric scattering from inhomogeneous random media of non-spherical scatterers under a pulse incidence is studied. The time-dependent Muller matrix solution of the vector radiative transfer for layered random media is derived. Co-polarized and cross-polarized bistatic and back-scattering are numerically calculated. The shape and intensity of polarized echoes depict well the inhomogeneous fraction profile of random scatterers. Its functional dependence upon the fraction profile, layer thickness, and other parameters are discussed. This technique is applicable to the reconstruction of inhomogeneous fraction profile and inversion of the media thickness.
