摘要： 双光梳测距技术具有测量精度高、测速快、非模糊范围大和可现场溯源的优势，在航天工程中具有广阔的应用前景，如航天器交会对接、卫星编队飞行、大型展开机构定位等。在货运飞船与空间站交会对接的任务场景下，提出了一种双光梳高精度测距技术空间应用与试验方案，介绍了双光梳测距技术的基本原理，对试验系统进行了架构设计，实现在400m范围内对空间动态合作目标优于100μm测距精度、1kHz测量带宽。进一步针对测距系统的关键参数进行了设计与仿真，对系统的空间环境适应性进行了分析，结果表明测距系统最大可实现19.5m/s相对运动速度下的高精度测距，满足搭载任务场景需求，为下一步双光梳测距技术的在轨试验与航天工程化应用提供了技术参考。

Abstract: The dual-comb ranging technique has the advantages of high precision，fast response speed，large unambiguity range and on-site traceability.It has broad applications in space missions，such as spacecraft rendezvous and docking，satellites formation-flying，positioning of large deployment mechanisms.Under the scenario of rendezvous and docking between cargo spacecraft and space station，a space application and test scheme of high-precision dual-comb ranging was proposed.Firstly，basic theory of dual-comb ranging was introduced，and the architecture of the test system was built.It is theoretically demonstrated that a precision of 100μm in the range of 400m，along with a 1kHz response speed，can be achieved.Further，the key parameters of the ranging system were designed and simulated，and the space environment adaptability of the system was analyzed.The results show that it can achieve high-precision measurement within a maximum speed of 19.5m/s，meeting the mission requirements.The analysis results provide a technical reference for the on-orbit test and aerospace engineering application.
