摘要: 北斗是中国独立研发的导航系统，其反射事件的数量和分布规律有特殊的优势，也是设计低轨道反射信号（low earth orbit-reflection，LEO-R）星座的重要指标。利用具有均匀性和稳定性优势的Walker架构，设计了LEO-R星座，实现基于北斗反射信号的全球海洋遥感探测。分析星座与北斗的几何关系，推导了北斗反射事件被覆盖的判断条件。提出了标记-遍历的镜点计算方法，定量分析星座参数对北斗反射事件数量和分布规律的影响，并模拟36 h的尼伯特台风场景作为探测对象。结果表明，星座的覆盖时间百分比为97.619 73%，最大重访时间为404.511 s，验证了该星座全球遥感探测的有效性。Abstract: BeiDou is developed by China independently, the distribution and number of its reflection events have special advantages, which is the important indicator of LEO-R(low earth orbit-reflection)constellation. By using the Walker architecture which has the advantage of the uniformity and stability to design LEO-R constellation, it can realize the global ocean remote sensing based on BeiDou reflected signals. The geometric relation between the constellation and BeiDou is analyzed and the judgment condition of the reflection events is also derived. The impacts of constellation parameters on the number and distribution of the BeiDou reflection events are quantitatively analyzed by proposing mark-traverse algorithm, at the same time, the chosed simulation scene is 36 hours Nepartak typhoon. The results show that the percentage of constellation coverage time is 97.619 73% and the maximum revisit time is 404.511 s, which validates the constellation good performance on the global remote sensing.
