    • A system for protecting ships from attack by an infrared-seeking missile is provided which comprises decoying the missile by deploying an aerosol. In one embodiment, the aerosol merely scatters a modulated light beam. Another embodiment deploys particles that can undergo an exothermic photochemical reaction when initiated by an ultraviolet laser. The laser projects an image of the ship onto the aerosol and at the same time causes the particles to generate sufficient heat to attract the infrared-seeking missile away from the ship. This system presents an infrared-decoy target with a suitable infrared image of appropriate spatial scale to mislead a missile with imaging capability. The spectral content of the decoy's image resembles that of a blackbody 20.degree.-50 .degree. C. above ambient, and has a brightness and spatial extent equal to the largest ships, approximately 10 kw/steradian, in the 3-5 and 8-12 micrometer bands. The present invention is simple to use, rapidly deployed, and capable of presenting a decoy target that can last at least a minute or more.
    • 提供了一种保护船舶免受红外线寻求导弹袭击的系统,其中包括通过部署气溶胶来摧毁导弹。 在一个实施例中,气溶胶仅散射调制的光束。 另一个实施方案是在由紫外线激光引发时,可以进行放热光化学反应的颗粒。 激光器将船舶的图像投射到气溶胶上,同时使颗粒产生足够的热量以吸引远离船舶的红外线导弹。 该系统提出了具有适当的空间尺度的合适的红外图像的红外诱饵目标,以误导具有成像能力的导弹。 诱饵图像的光谱含量类似于高于环境温度20°-50°C的黑体,其亮度和空间范围等于最大的船舶,大约10 kw / steradian,在3-5和8-12 微米带。 本发明使用简单,快速部署,并且能够呈现可以持续至少一分钟或更长时间的诱饵目标。
