RCS analysis of bomb-fins

The difference of the corner reflection effect between bomb-fins and ordinary rectangular corner reflector was analyzed. The computational formula of radar cross section (RCS) of the corner reflection effect of the bomb-fins was derived by using equivalent section method and was verified by means of computation for the scattering property of the bomb-fins synthetic model. The reflection coefficient was introduced in RCS formula of polygon plate coated with radar absorption materials (RAM) and the two coefficient were used to express the double absorption/reflection effect of the corner reflector. The scattering property of the model coated with RAM was calculated.
