摘要
研究了空间目标光学特性与空间目标、天基观测系统以及太阳之间的相对位置、目标自身参数之间的关系。通过建立的空间目标光学特性仿真系统实时显示了观测系统与目标卫星的距离、目标视星等以及太阳相位角的变化情况;通过STK软件实现了天基光学观测过程的三维可视化,动态地描述出了仿真时段内不同时刻观测效果的变化情况。将建模仿真与可视化结合为天基空间目标光学观测的研究提供了很好的思路。
The relationships between brightness and dimension and surface characteristic and view angle and distance are analyzed,and the position relationships between optical sensor and space-based objects and sun are discussed.Then the simulation system of visible light scattering characteristic of space-based objects is set up.The simulation system can demonstrate the change state of distance and photometric magnitude and the sun phasic angle at real time.At last, visualization is realized which can dynamically display the changes of the imaging effect during the different simulation periods.Combine simulation with visualization is a preferable method for analyzing the space-based optic surveillance.
