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。
UAV target radar detection, classification and identification studies need to support the polarization of the UAV scattering characteristics. In this paper, the indoor measurement of unmanned aerial vehicle with complex materials is studied to reveal the difference of the total polarization scattering between the UAV and the metalized model. Using the analytical method of component decomposition measurement, the consistent relationship between the UAV and the polarization scattering of the main components is expounded. It is proved that the fuselage and the wing directly affect the depolarization effect of the complete machine. The fuselage part is the cross polarization The main source of scattering.
