【摘要】 对导弹弹翼进行面元划分,采用物理光学法进行考虑弹翼耦合效应的RCS计算,结合计算弹体后向散射的物理光学法和等效电磁流法,采用综合相位法建立一种考虑角反射器效应的导弹RCS计算方法。对角反射器模型进行计算并与文献对比,验证了算法的正确性。并对导弹模型进行RCS计算与分析,结果表明,弹翼的后向散射和耦合效应对导弹RCS的贡献在大部分角度范围超过弹身的贡献,在导弹进行雷达隐身设计时需要重点考虑。更多还原

【Abstract】 In order to study the RCS characteristics of missile,and the effect of dihedral corner reflector,the physical optical( PO) method is used to calculate specular scattering,and the MEC method is used to calculate edge diffraction of the target. The algorithm for dihedral corner reflector is designed. The result of several typical dihedral corner reflectors is in agreement with the result from the literature. It proves the accuracy of the algorithm. A model of a certain missile is established. Through the program,the missile’s RCS characteristics of angle of pitch and azimuth angle is simulated. And the dihedral corner reflector has great influence on the missile’s RCS in the most direction.更多还原
