研究激光导星上行链路倾斜估计问题，核心方法是利用单基地配置的激光发射望远镜获取遥测数据，通过孔径尺寸分集结合线性最小均方误差估计器来解算，模拟得出不同湍流层下的残余误差，为相关研究提供了新方法。
AI 中文摘要
激光导星自适应光学无法直接测量倾斜，依赖自然导星限制了天空覆盖范围。我们提出仅通过在单基地配置下作为发射器和接收器运行的激光发射望远镜获取的遥测数据来估计上行链路倾斜。在接收光瞳内不同直径的同心圆盘上提取倾斜，产生不同比例混合上行链路和下行链路贡献的信号；这种孔径尺寸分集与线性最小均方误差估计器相结合，解开了上行链路分量。模拟显示，对于单个湍流层，残余误差为24毫角秒，对于两个湍流层，残余误差为34毫角秒。
英文摘要
Laser guide star (LGS) adaptive optics cannot directly measure tip-tilt (TT), forcing reliance on natural guide stars and limiting sky coverage. We propose estimating the uplink TT from telemetry acquired at the laser launch telescope alone, operated in a monostatic configuration as both emitter and receiver. Extracting TT over concentric disks of different diameters within the receiving pupil yields signals mixing uplink and downlink contributions in different proportions; this aperture size diversity, combined with an LMMSE estimator, disentangles the uplink component. Simulations show a residual error of 24 mas for a single turbulent layer and 34 mas with two layers.
