| 摘 要： | 翼面是飞行器对正向入射波的后向RCS的重要来源，为了减缩翼面的后向RCS，一般可在翼面的前缘改用吸波结构以减小翼面对后向的散射。在建立吸波结构前缘翼面的物理模型后，采用快速多极子方法和矩量法的混合方法，计算不同的金属介质分界面条件下的后向雷达散射截面，经过比较和分析，得出降低飞行器翼面后向雷达散射截面的较优方案。

| Abstract: | Wings are one of the important scattering sources on the aircraft. In order to reduce the RCS, the lossy material in the front edge of metal wings are applied. For reducing the complexity, the wings can be viewed as a two dimensional large electric objects consisting of both conductors and inhomogeneous dielectrics. Fast multipole algorithm(FMM) and methods of moment(MM) are used to work out the scattering fields. The RCSs of different wings are compared and examined. The results are obtained and can give strong predictive power for stealth technology of aircraft. |
