Remote Sensing of Layered Media: Perturbative Scattering Models

Electromagnetic Models for Remote Sensing of Layered Rough Media

Each region of the Earth’s crust can be morphologically modeled as a suitable layered structure, in which some amount of roughness is presented by every interface. Actually, propagation in stratified soil, sand cover of arid regions, forest canopies, urban buildings, snow blanket, snow cover ice, sea ice and glaciers, oil flood on sea surface, and other natural scenes can be modeled referring t...

Basic Studies in Microwave Remote Sensing by

The purpose of this research is to develop scattering models in support of microwave remote sensing of earth terrains with particular emphasis on model applications to airborne SAR measurements of forest. Practically useful surface scattering models based on a solution of a pair of integral equations including multiple scattering effects have been developed. Comparisons of these models with con...

Three-Dimensional Electromagnetic Scattering from Layered Media with Rough Interfaces for Subsurface Radar Remote Sensing

Perturbation Theory for Scattering from Multilayers with Randomly Rough Fractal Interfaces: Remote Sensing Applications

A general, approximate perturbation method, able to provide closed-form expressions of scattering from a layered structure with an arbitrary number of rough interfaces, has been recently developed. Such a method provides a unique tool for the characterization of radar response patterns of natural rough multilayers. In order to show that, here, for the first time in a journal paper, we describe ...

Rigorous modeling of ultrawideband VHF scattering from tree trunks over flat and. sloped terrain

Three electromagnetic models are employed for the investigation of ultrawideband VHF scattering from tree trunks situated over flat and sloped terrain. Two of the models are numerical, each employing a frequency-domain integral-equation formulation solved via the method of moments (MoM). A body-of-revolution (BoR) MoM formulation is applied for a tree trunk on a flat terrain, implying that the ...
