合成孔径雷达电子干扰技术综述

A review of electronic jamming technology for synthetic aperture radar

摘要:

合成孔径雷达（synthetic aperture radar, SAR）通过主动辐射电磁波，可实现全天时全天候对观测区域进行高分辨成像，被广泛用于情报侦察、战场探测、微波遥感、地形测绘等领域。目前，SAR在军事领域的应用愈加广泛，严重威胁了我重要目标的生存性和战略部署的有效性。如何对SAR进行有效干扰，压制或扰乱SAR系统的侦察、识别等功能，一直是雷达对抗领域研究的热点难点问题。为此，阐述了对SAR有源与无源干扰技术的发展现状，分析了现阶段有源与无源干扰技术的挑战与难点，对SAR干扰技术的发展趋势进行了展望，以期为相关领域的学者和工业部门提供有益参考。

Abstract:

Synthetic aperture radar (SAR) can achieve high-resolution imaging of the observation area all day and all weather by actively radiating electromagnetic waves, therefore, it has been widely used in the fields of disaster assessment, terrain mapping, intelligence reconnaissance, battlefield detection, etc.At present, the application of SAR in the military field is becoming more and more widespread, seriously threatening the survival of our important targets and the effectiveness of strategic deployments. In the field of electronic countermeasures, how to effectively interfere with SAR and how to suppress or disrupt the reconnaissance and detection functions of SAR have always been a hot and difficult issue. The development and current status of SAR active and passive jamming technology were elaborated in this article, and the difficulties of current active and passive jamming technology were analyzed. Finally, the development trend of SAR jamming technology were expected, which could provide a certain references for scholars and industrial departments.
