摘要
合成孔径雷达(SAR)是一种全天候、全天时、具备高分辨率的成像设备,被广泛应用于对敌侦察,为战场决策提供及时可靠的情报支持。如何压制和扰乱SAR设备的成像侦察,实现对高价值目标和要地的有效防护,已成为当前电子对抗领域的研究热难点之一。该文探讨了SAR干扰的技术进展和发展趋势,首先详细梳理了SAR干扰技术的发展脉络,然后结合仿真实验对比分析了典型SAR干扰样式的优缺点,最后总结了现有SAR干扰技术存在的不足,并指出其未来发展趋势,可为专家学者提供一定的参考。
Synthetic Aperture Radar(SAR)is an all-weather and all-time imaging radar with high resolution,which is widely used for enemy reconnaissance to provide timely and accurate intelligence for taking decisions during wars.It has become a hot issue in the contemporary electronic warfare to suppress and disorder the reconnaissance imaging of SAR equipment for protecting high-value targets and important strategic areas.This study discusses the development and future trend of SAR jamming techniques.First,the history of development of SAR jamming techniques is discussed and explained in detail.Then,the advantages and disadvantages of the typical SAR jamming models are comparatively analyzed together with simulation experiments.Finally,the current defects of the SAR jamming techniques are summarized and the future trend of the SAR jamming techniques is also pointed out,providing some reference for experts and scholars.
