摘要
提出一种新的合成孔径雷达有源欺骗干扰方法———基于移相调制的合成孔径雷达虚假图像干扰。对该方法的干扰原理进行了深入分析并进行了仿真实验。研究表明 ,新方法可以产生覆盖一定区域的包含大量地物信息的虚假图像 ,欺骗干扰效果远强于传统的虚假点目标干扰 ,具有很好的应用前景。
This paper deals with the problem of DECM(deceive electronic countermeasure) to SAR(Synthetic Aperture Radar).Through analyzing the characteristics of SAR echo signal , a new DECM approach(False Image Jamming Based on Phase Modulation)is proposed. Results of both theory and simulation show that the jamming effect of the new approach is much better than that of false point-target jamming.
