弹道目标红外成像是导弹预警信息处理的基础.提出了一种天基红外预警系统对弹道中段目标红外成像的仿真方法.首先建立了中段目标天基红外成像的点源成像模型;而后构建了基于STK/EOIR的弹道中段目标天基红外动态成像仿真架构;最后对中段目标(群)开展了多平台、多波段的红外成像仿真,分析得到了传感器对中段目标群动态成像特点.%Ballistic target infrared imaging is the basis for processing the early warning information of missiles.A simulation method was given for simulating the infrared imaging of space-based infrared warning system to ballistic midcourse target.First,the point source imaging model of space-based infrared imaging was established for midcourse target.Then,the simulation architecture of space-based infrared imaging was constructed for ballistic midcourse target based on Satellite Tool Kit/Electro-optical Infrared Sensor (STK/EOIR).Finally,simulation was carried out for the infrared imaging of midcourse target (group) on multiple platforms and multiple wavebands.Analysis was made to obtain dynamic imaging characteristics of the midcourse targets.
