Abstract :
Facet-based radar cross section (RCS) analysis codes have come to maturity in today´s high-frequency EM environment. Facet-based analysis is sometimes adequate for conventional high-signature object. However, in the prediction of a low-observable object, the significant RCS prediction errors-facet noise can occur when using facet models. In this paper, three kind of models are studied.
