Simulation for Detection of Anomalous Scatters under Inhomogeneous Canopy by Using the Mueller Matrix Solution of the Pulse Radiative Transfer

摘要

The Mueller matrix solution of vector radiative transfer for inhomogeneous random media of non-spherical scatterers under a pulse incidence is presented. Co-polarized and cross-polarized bistatic scattering echoes are numerically simulated. Temporally varying echoes can well identify volumetric and surface scattering mechanism and depict the inhomogeneous fraction profile of random scatterers. The effective canopy height inverted from the pulse echoes is discussed. Numerical simulation of pulse echo patterns demonstrates the applicability for detection of anomalous scatters under inhomogeneous canopy.
