RCS Analysis of Bomb-Fins

This paper analyzes the difference of corner reflection effect between bomb-fins and ordinary rectangular corner reflector , and derives the formula of RCS of the corner reflection effect of bomb-fins for engineering calculating using equivalent-section-method, and the formula is verified by means of calculating the scatter property of bomb-fins synthetic model. And the reflecting coefficient is induced to the RCS formula of polygon plate covered wiith radar absorption material (RAM), two coefficients are used to express the two times of absorption/reflection effect of the corner reflection;And finally the scatter property of the model covered with RAM is calculated with this reflection-coefficient-method.
