Le calcul rigoureux de la SER (Surface Equivalente Radar) monostatique d'un objet situé au-dessus d'une surface de mer monodimensionnelle (cas 2D) nécessite de résoudre un problème possédant un grand nombre d'inconnues. Pour ce calcul, une méthode numérique rapide récemment développée, nommée E-PILE (Extended Propagation-Inside-Layer Expansion), est combinée à la FB-SA (Forward–Backward with Spectral Acceleration). Deux objets sont considérés dans ce papier : l'obstacle cruciforme (la croix) et le cylindre. L'étude des résultats issus de la méthode E-PILE + FB-SA permet de bien comprendre les mécanismes physiques du couplage de l'obstacle et de la surface de mer. L'application visée est la détection d'obstacles pour la télédétection en milieu maritime.
The rigorous computation of the monostatic RCS (Radar Cross Section) of an object above a one-dimensional sea surface (2D case) needs to solve a problem involving a high number of unknowns. Thus, a recently developed fast numerical method, called E-PILE (Extended Propagation-Inside-Layer Expansion), was combined with FB-SA (Forward–Backward with Spectral Acceleration). Two objects are considered in this article: the cross and the cylinder. Results obtained from E-PILE + FB-SA allow us to understand the physical mechanisms involved in the coupling between the object and the sea surface.
