| 中文摘要:提出了一种天基预警系统对弹道中段目标红外探测的仿真方法。利用卫星工具箱的红外模块(Satellite Tool Kit/Electro-Optical Infrared Sensor, STK/EOIR)对中段目标红外辐射的特性进行了研究。首先,提出了基于STK/EOIR的弹道中段目标动态红外辐射特性仿真方法，分析了EOIR目标红外辐射的计算模型和传感器接收模型。然后,给出了典型目标在中波、中长波以及长波红外波段的红外辐照度的仿真结果。最后,对比分析了观测角、观测距离对天基凝视传感器接收目标红外辐照度的影响。仿真结果表明，中段目标红外辐射的强度能满足天基凝视传感器的探测灵敏度要求。 |

| Abstract:A simulation method of infrared (IR) detection of midcourse ballistic targets by spaceborne early warning systems is proposed. The IR radiation characteristics of midcourse targets are studied by using the infrared module of Satellite Tool Kit/Electro-Optical Infrared Sensor (STK/EOIR). First, the simulation method of dynamic IR radiation characteristics of midcourse ballistic targets based on STK/EOIR is proposed. The calculation model of IR radiation of EOIR targets and the receiving model of the sensor are analyzed. Then, the simulation results of IR irradiation of a typical target in mid-infrared waveband, mid and long infrared waveband and long infrared waveband are given. Finally, the influences of observation angle and observation range on the target IR irradiation received by spaceborne staring sensors are compared. The simulation results show that the IR radiation intensity of midcourse ballistic targets can meet the detection sensitivity requirements of spaceborne staring sensors. |
