摘要
中低轨天基红外星座是一种新型的能对自由段目标进行跟踪的导弹预警星座,太阳是影响其跟踪覆盖性能的重要背景条件。详细分析了太阳对跟踪传感器的影响条件、方式和大小,并进行了仿真验证。研究表明太阳对单颗卫星的影响较大,并且呈现周期性,但对整个星座的影响有限。
The space based infrared （SBIR） LEO ＆ MEO constellation is a new type of early warning constellation for ballistic missile, which can track a ballistic target of coast phase. The sun has unelectable impact upon its airspace coverage for tracking. The conditions, the manners and the extents of the sun＇s impact on the tracking sensors are analyzed, and the simulation verification has been carried out. The research shows that the sun＇ s impact upon single satellite is obvious and takes on periodicity,but the impact is finite on the whole constellation.
