基于空间光学探测的空间目标星等特性分析研究

利用STK对空间目标的轨道特性分析,模拟了太阳与空间目标观测面的夹角,空间目标在光照区的时间和空间光学望远镜与空间目标的夹角.利用黑体辐射定律,计算太阳在可见光区域的能流密度,通过建立平面目标可见光辐照度模型,推导了空间目标到达空间光学望远镜的辐照度模型,建立了一种汁算空间目标等效星等模型.通过建立的模型可以对正常工作的卫星和失效卫星判断区分.

The Research of Identification on Calculation Model of Equivalent Magnitude of Space Targets

This paper analyzes the orbit characters of space targets on STK platform, simulates the inclinations between the sun and space targets, the times of space targets in sunshiny areas and the inclinatioas between space-baaset telescope and space targets. According to Planek's law, energy flux density of the sun in visible region is calculated. Through establishing the visible light irradiance model for plane targets, the irradiance model of space targets and space-based telescope is derived. Finally,the calculation model of star magnitude of space targets is established. Through establishing the star magnitude can differentiate natural and disabled planet.
