Abstract: For the scattering from large convex bodies with discontinuities on surface, an accurate and highly efficient solution, i. e. the hybrid method is presented. The bistatic RCS of large ogive consisting of perfect conducting with coating of loss dielectric media on its surface partly as considering the axial illumination with = 0.03m has been analyzed and calculated.By using covering loss media coating to decrease the RCS of an object, certain meaningful conclusions are obtained.

Key words: discontinuity, ogive, RCS
