卫星激光测距（SLR）是目前卫星单点测量精度最高的测距技术，通常采用532 nm波长激光器，由1064 nm基频光倍频得到。而1064 nm波长激光在大气传输特性、远场光束特性、远场光的单位能量光子数和激光器功率等方面都较532 nm有优势，更有利于增强系统的探测能力，尤其在开展微弱信号目标的探测方面。进行了1064 nm波长卫星激光测距技术研究，分析了构建1064 nm波长卫星激光测距系统主要技术和难点，提出了相应的解决方案，在国内首先开展1064 nm波长高精度卫星激光测距实验，获得了初步的测量结果，为该测量技术发展和应用打下了很好基础。

Satellite laser ranging (SLR) is the most common satellite observation technology with the highest single shot measuring precision which usually uses 532 nm wavelength derived from 1064 nm laser. 1064 nm wavelength has many better properties than 532 nm in atmospheric attenuation, photon number, laser power, development and price, and so on, which is benefit to enhance the system detection ability, and carry out the goal of weak signal detection. The key technology and difficulties are presented in building up a SLR system with the wavelength of 1064 nm, and the corresponding solutions are put forward. With these technologies, the satellite laser ranging based on 1064 nm wavelength in China is successfully carried out for the first time and the experimental foundations have been laid for the further development and application in field of space targets observation.
