Influence of laser parameters on jamming effectiveness of IR imaging system

  • 摘要: 针对激光对红外成像系统的干扰效果是光电对抗领域的一个研究热点,采用波长10.6 m的CO2调谐脉冲激光器,通过漫反射板反射激光能量到像元数为320240的多晶硅非制冷焦平面红外热像仪上进行激光干扰红外成像系统的实验。在实验中研究了干扰激光能量、重复频率、波长、光斑大小等激光参数对干扰效果的影响,并从图像质量的角度分析了激光参数对干扰效果的影响。结果表明,随着干扰激光能量密度、重复频率、波长和光斑的增大,干扰效果提高。此外,漫反射干扰的效果证明这种干扰方式是可行的,该方式可避免干扰源成为未来将出现的反辐射光电制导武器的诱饵,为CO2激光干扰装备提供一种新的战术配置方法。
    Abstract: Jamming effect of laser on IR imager is an interesting research subject in electro-optical countermeasure. Jamming experiment and analysis were conducted. A pulsed CO2 laser with the wavelength of 10.6 m was used, and the laser was reflected to a polysilicon 320240 uncooled focal plane array (UFPA) infrared thermal imager through a diffuse plate. By adjusting the laser energy density, frequency, wavelength and the size of laser spot, as well as analyzing the jamming image quality, the influence of laser parameters on jamming effect was studied. The results show that the jamming effect is improved with the increasing of energy, frequency, wavelength and size of laser spot. Moreover, the jamming effect proves the feasibility of the diffuseness jamming, which avoids the interference source becoming the bait of the laser anti-radiation missiles and provides a new tactical solution for laser jamming.
