摘　　要：浮空角反射体是一种新兴的雷达无源干扰器材,受到各国装备研究机构的高度重视。为提升对浮空角反射体干扰机理的认知水平,在动态条件下针对其典型雷达目标特性展开研究。在构建浮空角反射体雷达回波信号模型的基础上,根据脉冲压缩方法对动态全极化一维距离像特性进行分析,通过脉冲多普勒处理研究了动态多普勒特性,借助极化角计算对动态极化特性进行讨论。研究结果揭示了在动态条件下浮空角反射体的雷达特征表现,对丰富该类型器材的基础理论具有重要意义。Airborne corner reflector is a new kind of radar passive jamming equipment,which is highly valued by equipment research institutions in various countries.In order to improve the understanding of the jamming mechanism of the airborne corner reflector,the typical radar target characteristics are studied in the dynamic perspective for the first time.On the basis of constructing the radar echo signal model of airborne corner reflector,the characteristics of dynamic all-polarized one-dimensional range profile are analyzed by pulse compression method.The characteristics of dynamic Doppler are studied by pulse Doppler processing.The dynamic polarization characteristics are discussed by calculating the polarization angle.The research results reveal the radar characteristics of airborne corner reflector in dynamic perspective,which is of great significance to enrich the basic theory of this type of equipment.
