通过建立机载合成孔径雷达(Synthetic Aperture Radar,SAR)工作模型,介绍有源假目标欺骗干扰的产生,在研究SAR欺骗式干扰的基础上针对转发的欺骗式干扰进行了分析研究,通过建立条带式SAR地面目标处成像模型,对欺骗式干扰产生的过程进行了研究,对转发的欺骗式干扰如何影响成像质量做了重点分析,在使用调频变标算法进行成像的基础上,利用仿真手段模拟实现了转发欺骗式干扰对成像质量的影响,证明使用该方法能够有效的保护己方的重要目标。
Through the establishment of the working model of Synthetic Aperture Radar (SAR), this paper introduces the generation of deceptive interference from active artificial targets, analyzes the deception jamming based on the research of SAR deception jamming, The imaging model of ground target SAR is studied. The process of deception jamming is studied, and how the deception jamming of forwarding affects the imaging quality is analyzed emphatically. Based on the imaging using FM algorithm, The simulation realizes the influence of forwarding spoofing on the imaging quality, and proves that using this method can effectively protect one’s own important goals.
