The invention provides a low-scattering carrier for an airfoil front edge RCS test, the low-scattering carrier comprises a front edge cover plate and a carrier main body which are detachably connected, the carrier main body and a carrier end face are of an integrally formed metal hollow structure, the front edge of the carrier main body is of a linear structure attached to an airfoil front edge wave-absorbing structure, and the front edge of the carrier main body is of a rectangular structure attached to the airfoil front edge wave-absorbing structure. The rear edge of the carrier body is of a linear structure parallel to the front edge. According to the low-scattering carrier, the drop-shaped design is adopted, the carrier end face and the carrier body are integrally formed, and the airfoil front edge and rear edge parallel structure is used, so that the influence of the edge on angular domain scattering assessment is reduced, and the vertical polarization and horizontal polarization electromagnetic scattering characteristics of the carrier are greatly reduced; and the stealth performance of the carrier in various radar environments is further improved. The low-scattering carrier provided by the invention has a good traveling wave suppression effect, and in an X wave band 0-50 degrees range, the RCS mean value of polarization in the horizontal direction can reach-45dBsm, and the RCS mean value of polarization in the vertical direction can reach-40dBsm.
本发明提供了一种翼面前缘RCS测试的低散射载体,所述低散射载体包括可拆卸连接前缘盖板和载体主体,所述载体主体和载体端面为一体成型的金属中空结构,所述载体主体的前缘为与翼面前缘吸波结构贴合的直线型结构,所述载体主体的后缘为与前缘平行的直线型结构。本发明的低散射载体采用水滴形设计,载体端面和载体主体一体成型以及使用翼面前缘和后缘平行结构,减小了边缘对考核角域散射的影响,大大降低了载体的垂直极化和水平极化电磁散射特征,进一步提高载体在多种雷达环境下的隐身性能。本发明的低散射载体具有很好的行波抑制作用,在X波段0‑度‑50度范围,水平方向极化的RCS均值可达到‑45dBsm,垂直方向极化的RCS均值可达到‑40dBsm。
