摘要: MS1和MS2试验星是我国首批设计寿命10年的中高轨导航卫星，为提高在轨精度和实现卫星精密定位，作为舱外有效载荷，两颗卫星均标配搭载了激光反射器。卫星激光反射器光学设计应考虑远场衍射等物理光学影响，不能仅考虑几何光学理论设计。以试验星反射器为例，基于角反射器光学远场衍射能量分布理论为基础，采用最大雷达截面法进行反射器尺寸优化，利用角度补偿法进行速差补偿角设计，对反射器表面加工精度、反射表面特性、切割方式等光学参数进行优化分析计算，并通过合理的机械结构和材料设计，解决了高量级力学环境、330℃高低温度交变、10年空间辐照寿命等环境适应性问题。试验星光学测试结果表明：参数设计合理，可实现远场环带能量在预定观测区域的最大化，在轨观测数据表明反射器工作正常，测距精度、测距范围等指标满足预期设计，理论设计和实践相符，这对今后同类激光反射器的设计具有借鉴和指导意义。Abstract: Lives of MS1 and MS2 are 10 years, they are first high orbit navigation satellites of China. In order to improve orbit accuracy and realize the precise positioning of satellites, the two satellites were equipped with laser retro-reflectors. For the optical design of laser retro-reflector, the far-field diffraction of physical and optical properties should be considered besides the design theory of geometrical optics. Taking the test satellite reflector as an example, based on the corner reflector optical far field diffraction energy distribution theory, the reflector size was optimized by using the maximum radar cross section method, the laser retro-reflector aberration was compensated by the angle compensation method, the optical parameters, such as the reflector surface machining accuracy, surface reflection characteristics, cutting mode were optimizated and analyzed, and environment adaptability problems, for example, the high level mechanical environment, 330℃ high temperature, alternating 10 years life space radiation, were solved through the rational design of the mechanical structure and materials. Optical test results show that the parameters are reasonable, can realize the far field energy maximization in predetermined observation area, at the same time, observation data on orbit shows that the reflector works properly, ranging accuracy, range of indicators meet the expected design and the theory is in according with practice, this provideds certain reference and guiding for the design of similar laser reflector in the future.
