空间光链路捕获中各种搜索方法的性能和抗抖动鲁棒性分析
Analysis of performance and robustness against jitter of various search methods for acquiring optical links in space
摘要：
我们讨论了在空间中使用专用采集传感器采集光链路的各种方法。统计模型的开发和简单的分析方程推导出一个单一的和双螺旋扫描方法之间的性能比较，以及之间的顺序和并行采集的链接链。简单推导的分析方程允许相关的基本搜索参数，如轨道宽度，方差的不确定性分布，捕获半径和扫描速度的概率，在特定的时间内获取的链接。我们还评估了由于光束抖动而无法获得链路的概率，并推导出一个简单的分析模型，该模型允许确定给定光束重叠的最大可容忍抖动和所需的成功概率。所有结果都通过蒙特卡罗模拟进行了验证，并应用于GRACE FO任务的具体实例。
英文摘要：
We discuss various methods for acquiring optical links in space using a dedicated acquisition sensor. Statistical models are developed and simple analytical equations derived that compare the performance between a single and dual spiral scan approach as well as between sequential and parallel acquisition of link chains. Simple derived analytical equations allow relating essential search parameters such as track width, variance of the uncertainty distribution, capture radius and scan speed to the probabilities of acquiring the links within a specific time. We also assess the probability of failing to acquire a link due to beam jitter and derive a simple analytical model that allows determining the maximum tolerable jitter for a given beam overlap and required probability of success. All results are validated by Monte Carlo simulations and applied to the concrete example of the GRACE FO mission.
