“…Taking synthetic information of the amplitudes and phases of multipolarized scattered waves, inversion of the characteristic parameters of complex terrain surface has become an essential issue of quantitative remote sensing. Particularly, in the field of physical modeling for natural scene remote sensing, the first-order Mueller matrix solution of the vector radiative transfer (VRT) theory for a layer of nonspherical particles as Manuscript [3]. As pulse echo profile provides rich temporal information showing the process of wave propagation and scattering through complex media, and might identify contributions from different scatter layers or different volumetric and surface scattering, the wideband pulse propagation problems become important in remote sensing and wireless communication.…”

Under a polarized pulse wave incidence, the temporal Mueller matrix solution from vector radiative transfer (VRT) equation for a layer of nonspherical particles above randomly rough surface is constructed. The system response function based on the Mueller matrix solution is developed, which takes into account the scattering intensity matrix of the canopy, attenuation coefficient matrix through the canopy, scattering intensity matrix of underlying ground surface, and echoes time delay. This system response model preserves consistence with the Mueller matrix solution. To evaluate the system response function from the wave profiles of the received pulse echoes, an adaptive nonlinear estimation method (ALM) is proposed. When the pulse echoes are received, it yields the system response function, i.e., four system parameters. These system parameters are used to invert multiparameters of the vegetation canopy and underlying rough surface, which include the canopy depth, scatterers size, orientation, density and dielectric constant, and the surface roughness and dielectric constant. Numerical examples show good performance of our method as a tractable approach for multiparameters inversion. Potential application and some issues of multiparameters inversion are discussed. An envisaged sensor and platform for practical realization is proposed.Index Terms-Adaptive nonlinear estimation method (ALM), multiparameter inversion, polarimetric pulse echoes, system response function, vector radiative transfer (VRT).

“…The Mueller matrix solution of vector radiative transfer has been studied for polarimetric scattering from a layer of random nonspherical particles [3]- [5]. However, as the incidence is a plane pulse, it leads the problem of the pulse echoes for polarimetric scattering from random scatterers media and the temporal Mueller matrix solution.…”

Polarimetric scattering from inhomogeneous random media of nonspherical scatterers under a pulse incidence is studied. The time-dependent Mueller matrix solution of vector radiative transfer for layering random media is derived. Copolarized and cross-polarized bistatic and back-scattering are numerically calculated. The shape and intensity of polarized echoes well depict the inhomogeneous fraction profile of random scatterers. Its functional dependence upon the fraction profile, layering thickness, and other parameters are discussed. This technique is applicable to reconstruction of inhomogeneous fraction profile and inversion of the media thickness.Index Terms-Inhomogeneous random media, polarimetric scattering, pulse echo, temporal Mueller matrix.
