| 摘要: |
| 合成孔径雷达(Synthetic Aperture Radar，SAR)是一种全天候、全天时、具备高分辨率的成像设备，在军用领域和民用领域均有重要的应用价值。SAR在军事上被广泛地应用于发现各类战略性目标如坦克、部队、巡逻艇、敌方武器系统部署以及其它重要的战略物资。在民用领域，SAR被用于地形测绘、预防各种天气现象如冰雹、洪水、干旱、飓风等。SAR技术的不断进步为重要军事目标的防御工作带来了极大的挑战，如何对SAR进行有效干扰，降低SAR对军事目标的检测与识别性能，从而保障军事目标能安全、高效地进行军事任务，仍是一个亟待解决的难题。本文阐述了对SAR干扰技术的发展现状，分析了现阶段SAR干扰技术的挑战与难点并对其发展趋势进行了展望，以期为相关领域的研究人员提供有益参考。 |

| Abstract: |
| Due to its excellent resolution imaging ability and good adaption to various weather and time, Synthetic Aperture Radar (SAR) holds significant relevance in both military and civilian. In the military field, SAR is widely used to discover various important strategic targets, such as tanks, forces, patrol boats, deployment of enemy weapon systems and other important strategic materials. In the civilian field, SAR is used for terrain mapping, preventing various weather phenomena such as hail, floods, droughts, hurricanes, etc. The continuous progress of SAR technology has brought great challenges to the defense of important military targets. The urgent problem of how to interfere with SAR, reduce its detection and recognition performance on military targets, and guarantee that these targets can carry out military tasks safely and efficiently remains unresolved. This paper elaborates on the current development status of SAR countermeasures technology, analyzes the challenges and difficulties of SAR countermeasures technology at the current stage, and looks forward to its development trends, in order to provide useful references for scholars sectors in related fields. |
