摘要
天基红外系统(SBIRS)是美导弹防御系统的重要一环,能对助推段的进攻弹进行预警和弹道预报.在红外探测器工作原理的基础上,建立了主动段发动机喷管辐射、蒙皮辐射、尾焰辐射和背景辐射的模型,推导了总辐射亮度的计算公式,分析了SBIRS的探测距离.
SBIRS is an important part of the National Defense System of United States, which is mainly for early warning and forecasting of ballistic trajectory in booster stage. Based on the knowledge of the working mode of infrared detector, The model of propulsion nozzle radiation, coating radiation, wake flame radiation and background radiation is established, and the total radiation luminance is derived. The detecting range of SBIRS is analyzed.
