Radar scattering characteristics is an important researching content of military target. It is always very difficult to deal with simulation of electromagnetism field , especially to analyze the monostatic RCS characteristics. Aiming at a kind of complex & electrically large size target , this paper reasonably estimated its multi-point monostatic RCS using smaller resources by adopting the electromagnetic calculation software FEKO. This work succeeded on the analysis and optimization choice to typical high frequency algorithm theory, combined with the prediction precision and efficiency .This project has an important value in engineering application.
