摘要
推导了中低轨天基红外星座中单颗卫星基于自由段跟踪时的空域覆盖体积与星下黑体积,研究了其随轨道高度变化的规律,分析了存在切地角影响时的体积变化,并进行了计算。
The covering volume and the subjacent blind zone volume of single satellite of the space based infrared low earth orbit（LEO） medium earth orbit（MEO） constellations when tracking a target of coast phase were deduced in this paper.The volume changes with the changes of the orbit altitude were studied.The volume change within various incision angle was discussed.The computation of some examples was done at last.
