【摘要】：为了提高深空中红外探测器探测波段选择的效率以及反映目标真实的在轨状态,文中研究了空间目标动态红外图像的生成技术以及双波段红外图像的仿真。结合从STK获得的空间目标的运行轨迹和姿态数据以及从3DS MAX获得的目标模型数据提出了一种进行空间目标红外成像仿真的方法。首先分析了深空背景中目标的红外辐射特性以及目标在中波和长波两个波段中的辐射特性,为探测器波段参数的选择提供了依据;然后介绍了用节点网络法求解热平衡方程的方法并且简化了求解过程,提高了效率;最后阐述了空间目标红外成像系统的理论模型,实现了空间目标的红外可视化建模与仿真。仿真图像对新型系统的研制和红外图像处理算法的研究有重要的意义。
[Abstract]:In order to improve the efficiency of detecting band selection for deep air infrared detectors and to reflect the real in-orbit state of the target, the generation technology of dynamic infrared images of space targets and the simulation of dual-band infrared images are studied in this paper. Based on the trajectory and attitude data obtained from STK and the target model data obtained from 3DS MAX, a method for infrared imaging simulation of space targets is proposed. Firstly, the infrared radiation characteristics of the target in the deep space background and the radiation characteristics of the target in the medium and long wave bands are analyzed, which provides the basis for the selection of the detector band parameters. Then the paper introduces the method of solving heat balance equation with node network method and simplifies the solving process and improves the efficiency. Finally, the theoretical model of infrared imaging system for space object is described, and the infrared visual modeling and simulation of space target is realized. Simulation image is of great significance to the development of new system and the research of infrared image processing algorithm.
