摘　　要：航空光电载荷在专业领域中的作用越来越重要,其结构与功能越来越复杂,造价也愈加昂贵,相关仿真技术的研究越来越迫切。介绍了航空光电载荷的结构组成、系统功能和工作原理以及现有仿真技术的不足。针对图像制导仿真系统中最关键也最迫切需要的环节——光电载荷成像仿真,基于正射影像图,结合了飞行力学坐标系统与光电载荷坐标系统,通过构建中间环节的数学模型,分析不同坐标系下的姿态转换关系,采用与实际情况一致的光电载荷系统架构,通过对成像过程的分析完成了成像区域的判断与确定,并且利用反解法完成了对成像区域像点的处理,从而完成了航空光电载荷的成像仿真。联合仿真验证了所提仿真系统的正确性与严谨性,在大型制导仿真系统中起到了重要作用。In professional fields of modern military,the role of airborne optoelectronic payload is more and more important,its structure and function are more and more complex,the cost is more and more expensive,and the research of relevant simulation technology is more and more urgent.The structure composition,system function and working principle of airborne optoelectronic payload as well as the deficiency of existing simulation technology are introduced.Aiming at one of the most critical and urgently needed links in the image guidance simulation system-airborne optoelectronic payload imaging simulation,based on orthophoto and combining the flight mechanics coordinate system and optoelectronic payload coordinate system,the mathematical model of the intermediate link was built to analyze the attitude transformation relationship in different coordinate systems,and the optoelectronic payload system architecture consistent with the actual situation was adopted.Through the analysis of the imaging process,the imaging region is judged and determined,and the inverse method is used to complete the processing of pixels in the imaging region,so as to complete the imaging simulation of airborne optoelectronic payload.The co simulation verifies the correctness and rigor of the simulation system,which plays an important role in the large-scale guidance simulation system.
