Estimation of Emissivity and Scattering Coefficient of Vegetation from Measured Dielectric Constant at Microwave Frequencies
نویسنده
چکیده
The emission from the vegetation canopy depends on the type of vegetation and the frequencies at which the emission is measured. For studying the vegetation canopy of a tree, the dielectric constant of its constituent is measured at microwave frequencies. In this study the dielectric constant is measured using waveguide cell method and its scattering coefficient is estimated using perturbation model for slightly rough surface. The emissivity is estimated using emissivity model. The results obtained are useful for microwave remote sensing of vegetation canopy.

متن کاملDielectric and Radiative Properties of Sea Foam at Microwave Frequencies: Conceptual Understanding of Foam Emissivity
Foam fraction can be retrieved from space-based microwave radiometric data at frequencies from 1 to 37 GHz. The retrievals require modeling of ocean surface emissivity fully covered with sea foam. To model foam emissivity well, knowledge of foam properties, both mechanical and dielectric, is necessary because these control the radiative processes in foam. We present a physical description of fo...
