摘　　要：在电子对抗领域,全方位高效干扰能力具有重要的应用需求。基于范阿塔阵列的强回溯能力,提出了一种基于阿基米德多面体构型的范阿塔回溯阵,并根据多面体构型设计了正六边形分布的范阿塔阵列单元,分析了在不同来波角度、不同阵元数量及不同入射波频率下多面体范阿塔阵列在全向空间上的散射特性。研究结果表明,此多面体范阿塔阵列结构紧凑,散射场在X波段频率范围内的强散射空间占比均超过85%,具有全向散射的优势,在全向回溯能力要求较强的场景具有良好的应用潜力。In the field of electronic countermeasures,the omnidirectional efficient jamming capability has important application requirements.Based on the strong backtracking ability,a Van Atta backtracking array based on the Archimedean polyhedral configuration is proposed,and an ortho-hexagonal Van Atta array cell is designed.The scattering characteristics of polyhedral Van Atta array in omnidirectional space are analyzed under different incoming wave angles,numbers of array elements and incident wave frequencies.The results show that this polyhedral Van Atta array has the advantages of compact structure.The strong scattering space ratio of the scattering field in the X-band frequency range is over 85%,which has the advantage of omnidirectional scattering capability and good potential for application in scenarios where omnidirectional backtracking capability is required.
