| 摘 要： | 全极化转发式假目标在极化域上具有逼真的雷达目标特性,给现代导弹防御系统构成了严重威胁。文章综合考虑在干扰机侦收雷达信号与雷达接收干扰信号时的极化基变换,修正了全极化转发式假目标在后向散射坐标系下的数学模型,分析了全极化转发式假目标的互异性与非奇异性质。结果表明,对于常见的单站极化雷达,全极化转发式假目标具有恒定的同极化比和共交极化比,这些确定属性能够为真假目标的极化鉴别提供可靠依据。

| Abstract: | The full-polarization repeater decoys are dangerous to modern defense system for their similarities to real targets of radars in polarization domain.Considering polarization basis transforms occur while the jammer receives the radar signal and the radar receives the jamming signal,the mathematical model of the full-polarization decoy in coordinate system of BSA is revised in this paper,and then its properties,such as reciprocity and nonsingularity are analyzed.The results show that the full-polarization dec... |
