以SBV为系统原型,在对天基光学空间目标监视工作机理进行分析基础上,充分考虑传感器恒星跟踪和目标星历两种工作模式特点,设计天基光学监视图像仿真结构和流程。分别对背景恒星、宇宙射线以及空间目标进行仿真模拟,并针对点扩散和空间目标运动拖尾问题进行改进,在模拟生成的仿真图像序列内能够更加充分反映空间目标点扩散和帧内运动特性
Taking SBV as the prototype of the system, based on the analysis of the working mechanism of the space-based optical space target monitoring, the structure and process of the space-based optical monitoring image simulation are designed considering the characteristics of the sensor stellate tracking and the target ephemeris. The simulation of background stars, cosmic rays and space targets are respectively carried out. The problems of point spread and motion tailing in space target are improved. The simulation results of the simulated images can reflect the spatial target spread and the motion characteristics more fully
