Entropy, alpha and anisotropy (H/alpha/A) of the polarimetric target decomposition of Cloude and Pettier has been an effective and popular tool for polarimetric SAR image analysis and geophysical parameter estimation. However, multi-look processing can severely affect the values of these parameters. In this paper, a Monte Carlo method is used to evaluate the multi- look effect on these parameters...
Retrieval of soil moisture under corn canopies has been investigated by many researchers and is still a problem that is not fully assessed. Corn is an organized canopy. This feature produces effects not observed from natural canopies. One such effect is the dependence of sensor response on the azimuthal direction. The aim of this study is to explore these distinguishing effects by Monte-Carlo simulations.
The difference field RCS (d-RCS) has been defined to analyze the scattering from the target above a rough surface. The electric field integral equations (EFIEs) of the difference induced current on the rough surface, the induced electric current and magnetic current on the dielectric target under a TE wave incidence are derived. A small portion of the rough surface towards the target along the specular...
