Evaluating the RCS Contribution of Geometrical Singularities: an Analytical Model

Autor: Pascal Pagani, Alexandre Corazza, Sylvain Morvan

Publikováno v: 2020 14th European Conference on Antennas and Propagation (EuCAP).

In the context of radar detection, the assessment of Radar Cross Section (RCS) requires computing the scattered electromagnetic field using numerical solvers. In order to study the potential contribution of geometrical singularities to the object’s

Autor: Fabien Degery, Sylvain Morvan, Olivier Vacus

Publikováno v: 2016 10th European Conference on Antennas and Propagation (EuCAP).

The Characteristic Mode Theory is a valuable tool in RCS analysis. Although the mathematical framework is established in the context of PEC objects, we apply the eigenvalue decomposition on Scattering Operators of coated objects, which coating is mod
