弹翼角反射器效应的雷达散射截面分析

RCS Analysis of Bomb Fins

分析了弹翼与一般直两面角的角反射器效应的不同，从等效截面法分析一般直两面角角反射器效应的雷达散射截面（ＲＣＳ），推导出用等效截面法分析弹翼角反射器效应的工程计算公式，通过计算弹翼、弹体组合的侧向散射特性进行了验证；引入涂敷吸波材料的平板ＲＣＳ的反射系数计算方法，采用两个反射系数表示角反射器效应的两次吸收／反射效应，最后用反射系数法分析了涂敷吸波材料后的弹翼散射特性．

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.
