摘要
为了使空间目标红外成像仿真尽量反应实际在轨工作状态,文中综合考虑目标自发辐射、太阳光辐射、地球辐射和地球反照的影响,结合空间目标在轨单点经纬度姿态数据、材料数据、探测器数据等先验信息,提出了一种空间目标在轨红外成像仿真技术。首先,阐述了空间目标红外成像仿真的理论模型。然后,以某简单立方体卫星为例,进行了在轨红外成像建模与仿真。所提出的空间目标红外成像仿真方法对空间目标探测、识别与跟踪算法的研究具有重要意义。
In order to make the infrared images of space target indicating its active state in orbit as real as possible, the contribution of the target spontaneous emission, the solar radiation, the earth radiation and the earth albedo radiation were considered. Combined with the information of the space target attitude and the detector parameters in orbit, a kind of infrared imaging simulation method was proposed in this article. Firstly, the method which is used to simulate the infrared imaging was explained in detail. Then, the method was used to simulate the infrared imaging of a simple cube satellite. The emulation results show that the method is feasible to simulate the infrared imaging of the space target, which has significant sense for the researches of target detection, recognition and tracking techniques.
