面源红外诱饵已经发展成为对抗红外成像制导导弹的一种有效手段,通过红外景象生成方式模拟逼真的动态干扰场景来进行半实物仿真试验是检验、评估红外成像制导导弹抗干扰性能的重要途径。以红外景象生成图像的分析为基础,首先建立了面源红外诱饵与来袭导弹之间的距离模型,然后依据相互距离的变化研究了干扰图像的面积变化模型、位置变化模型和亮度变化模型。最后按照仿真流程进行了面源红外诱饵的图像生成,并对干扰图像的面积、位置和亮度变化进行了仿真分析。结果表明,模拟生成的干扰图像较逼真地再现了实战干扰场景。

Surface-type infrared decoy has been an effective measure on countering IR imaging guided missile. Hardware-in-the-loop simulation with dynamic jamming scene from IR scene generator is an important way to verify and evaluate the countering jamming capability of IR imaging guided missile. Based on the analysis of IR generating image, the model of distance was firstly built, and according to the change of the distance, the area model, the position model and the lightness model of the jamming image were studied. At last, the image of surfacetype infrared decoy was generated following the simulation flow, and the simulation analysis about the area, the position and the lightness of the jamming image were conducted. The results demonstrate that the simulation jamming image vividly reproduces the real jamming scene in the warfare.
