摘要
隐身结构是指由蒙皮和多种内部材料组成的、能满足承载要求、并具有明显降低雷达散射截面的结构。本文首先阐述了一种典型的翼面隐身结构方案。为了进一步挖掘该隐身结构减缩RCS的潜力,应用基于代理模型的优化策略,对其进行电磁散射特性优化设计。研究结果表明,经过优化设计后,在方位和频域上能显著降低翼面隐身结构RCS。基于代理模型的优化策略是一种有效的隐身结构低RCS优化策略。
The low detectable wing structure is a type of the structures consisted of skin and varieties of internal materials, and has low radar cross section （RCS） by considering stress and other requirements. In this paper, a wing structure with low detectability is illustrated. To improve its capacity of reducing RCS, the efficient optimization design based on the surrogate models for electromagnetic scattering is carried out. Results indicate that after the optimization, the RCS of the low detectable wing structures is radically reduced. The optimization design based on the surrogate models is a valid strategy for reducing the RCS of wing structure with low detectability.
