为降低低轨导弹预警卫星的虛警概率,文中在分析弹道导弹主动段红外辐射特征的基础上,通过建立尾焰的几何特征模型和红外特征模型来描述导弹主动段的红外成像特征,并运用模型计算尾焰的红外辐射分布,构建了导弹尾焰的仿真图像,仿真图像能够准确反映导弹尾焰的红外图像真实情况,为有效识别导弹,提高导弹预警的准确性提供重要参考。

In order to reduce the false alarm probability of low earth orbit missile early warning satellite, on the basis of analyzing the infrared radiation characteristics of the active section of ballistic missile, infrared imaging characteristics of missile active section were described through the establishment of the geometric feature model and infrared feature model of tail flame. By using the model, the infrared radiation distribution of tail flame was calculated, and the simulation image of missile tail flame was constructed. Simulation images could accurately reflect the real situation of the infrared image of missile tail flame, and provided important references for effective identification missile and improving the accuracy of missile early warning.
