摘要: 无人机目标的雷达检测、分类和识别研究需要无人机的极化散射特性支撑。该文通过对复杂材质无人机的室内测量研究,揭示了无人机与金属化模型的全极化散射特性差异。利用部件分解测量的分析方法,阐述了无人机与主要部件极化散射一致性关系,证明了机身、机翼直接影响整机的退极化效应,其中机身部位是整机交叉极化散射的主要来源。Abstract: Knowledge of target polarization characteristics is valuable for radar target detection, classification, and identification.We conducted experimental research on an Unmanned Aerial Vehicle (UAV) with complex materials and structures to determine the differences in polarimetric scattering between the UAV and its perfect electric conductor model.To illustrate the coherence of the entire UAV and its components using polarimetric scattering, we measured and analyzed each part.The results reveal that the airframe and aerofoils directly influence the depolarization, and that the polarimetric scattering characteristics of the airframe represent the primary source for the whole UAV.
