Propagation and remote sensing / Propagation et télédétection Monostatic Radar Cross Section of an object above a sea surface from a rigorous method

TherigorouscomputationofthemonostaticRCS(RadarCrossSection)ofanobjectaboveaone-dimensional sea surface (2D case) needs to solve a problem involving a high numberof unknowns. Thus, a recently developed fast numerical method, called E-PILE (ExtendedPropagation-Inside-Layer Expansion), was combined with FB-SA (Forward–Backward withSpectralAcceleration).Twoobjectsareconsideredinthisarticle:thecrossandthecylinder.Results obtained from E-PILE
