对SAR的转发欺骗式干扰仿真研究

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。

Simulation Study on Repeater Deception Jamming of SAR

Based on the side looking mode of Synthetic aperture radar, the theory of fake tagert deception jamming was described. The repeater deception jamming of synthetic aperture radar based on the deception jamming was analized, a model of STRIP SAR imaging was established, the process of deception were analized, and the outcome of repeater deception jamming were given, the chirp scalling algorithm were used to test the effect of jamming, the RPJ were simulated by matlab and the consequences were given, the test was a good proven that the RPJ can protect the important target form reconnaissance.
