摘要: 为确保重要目标的信息安全,提出一种基于脉间分段随机移频的合成孔径雷达(SAR)干扰技术,该技术可在距离向产生若干条似噪干扰条带,脉间分段数决定条带的个数,移频量决定条带的位置和宽度,克服固定移频干扰无法掩护分布式目标的缺点,实现随机移频干扰条带单一的突破,且移频量的随机变化使得SAR无法找出移频规律,难以采取相应的对抗措施。针对干扰技术的特点,建立了具体的应用模型,给出该技术的实施步骤和方法。仿真实验验证了上述理论和方法的有效性和优越性。

Abstract: In order to ensure the safety of intelligence in important place, a jamming approach to synthetic aperture radar (SAR) based on inter-pulse subsection random frequency-shift technique is presented. The technique can produce several noise-like jamming swathes in range direction, of which number is determined by the number of inter-pulse subsection. The position and width of the jamming swathe are determined by frequency shift. The proposed technique overcomes the defect of the conventional fixed frequency-shift jamming which can’t protect distributed target, and produces several jamming swathes compared with random frequency-shift technique which can produce only one jamming swathe. Meanwhile, because of the random change in frequency shift, it is difficult for SAR to find the frequency shift rule and take the corresponding countermeasures. An application model is established, and the implementation steps and method of the technique are provided. The availability and advantages of this method are proved through the simulation experiments.
