Radar Active Deception Jamming Recognition Method Based on the Time-varying Polarization-conversion Metasurface
-
摘要: 聚焦雷达对抗中极化信息获取与利用的应用需求，该文研究了基于极化时变调控表面的有源欺骗干扰辨识方法。首先，设计了一套在9.6～10.1 GHz频带内支持3 bit相位量化的各向异性相位调制表面，通过优化相位调制编码序列，实现了极化态按需调控。然后，将极化调控表面加装在单极化雷达天线上，使天线发射和接收电磁波的极化态沿特定极化轨道变化，通过提取目标与有源欺骗干扰的极化域差异，实现两者辨识。仿真分析表明，在3种不同的极化轨道约束下，干扰与目标均具有显著的聚类效应，可获得稳定的干扰辨识效果。相较于依赖双极化或全极化雷达体制的干扰辨识方法，该文所提方法兼具低成本与高效性，在雷达抗干扰中具有很大的应用潜力。Abstract: In this study, aiming at fulfilling the requirement of polarization acquisition and utilization, a method for active deception jamming recognition based on the time-varying polarization-conversion metasurface is investigated. First, an anisotropic phase-modulated metasurface supporting 3-bit phase quantization in the 9.6～10.1 GHz frequency band is designed. By optimizing the periodical phase coding, the polarization state can be converted on demand. And then, loading the polarization-conversion metasurface on a single polarization radar antenna so that the polarization states of the antenna can change along a specific trajectory. By extracting the difference in the polarization domain between target and active deception jamming, the active deception jamming could be distinguished from the radar echo. The simulation results show that under the constraints of three different polarization trajectories, the active deception jamming and targets exhibit a significant clustering effect, and the identification effect is stable. Compared with jamming identification methods that rely on dual-polarization or full-polarization radar systems, the proposed method has both low cost and high efficiency, which has great application potential in radar anti-jamming.
