Scattering and emission from inhomogeneous vegetation canopy and alien target by using three-dimensional vector radiative transfer (3D-VRT) equation

JIN Ya-qiu LIANG Zi-chang(Center for Wave Scattering and Remote Sensing Fudan University,Shanghai 200433, China)  
To solve 3D-VRT equation for the model of spatially inhomogeneous scatter media, the finite enclosure of the scatter media is geometrically divided, in both the vertical z and horizontal (x,y) directions, to form very thin multi-boxes. The zero-th order emission, first-order Mueller matrix of each thin box and an iterative approach of high-order radiative transfer are applied to deriving high-order scattering and emission of whole inhomogeneous scatter media. Numerical results of polarized brightness temperature at microwave frequency and under different radiometer′s resolutions from inhomogeneous scatter model such as vegetation canopy and embedded alien target are simulated and discussed.
