基于虚假场景的合成孔径雷达干扰方法研究

Study on SAR jamming technique based on deceptive scene

虚假场景干扰是对合成孔径雷达(SAR)系统进行有效干扰的重要技术。针对机载SAR系统,介绍了虚假场景干扰的信号形式和产生方法,着重研究了干扰时应该考虑的一些关键因素,分析了雷达定位误差对干扰效果的影响,提出了干扰布阵的方法,解决了实施虚假场景干扰时可能遇到的问题。

Deceptive scene jamming is an initial jamming technique for SAR system. This paper starts from the point of airborne SAR, studies the signal form of the deceptive scene jamming, as well as the generation of the deceptive signal, then studies several key factors necessary for implementation, discusses the configuration of jammers and the effects of the location error of radar, solves several possible problems within implementation.
