摘　　要：卫星光通信具有高速率、大容量、高保密性等优点，正成为卫星通信技术的重要发展方向，并逐渐走向工程化，以此为背景对卫星光通信地面接收技术进行了综述。首先对光通信地面接收技术研究的重要性进行了阐述；介绍了国内外星地光通信技术的进展，给出了卫星地面激光接收系统的组成及工作流程；分析了关键技术，如高精度捕获、跟踪、瞄准（ATP）技术、高灵敏度抗干扰光通信接收技术、大口径光学天线设计技术等，讨论了开展卫星光通信地面接收技术研究的难点，最后对光通信地面接收技术的发展前景进行了展望。Due to the characteristics of high speed, large capacity and high security, the satellite optical communication is becoming an important development direction for satellite communication, and is being gradually engineerized. Based on this background, an overview of ground receiving technology of satellite -to -ground optical communication is given. Firstly, the importance of researching ground receiving technology of optical communication is discribed, then its status and developing trends in china and overseas are introduced, giving the composi- tion and workflow of ground receiving system. The key technologies are then analyzed, such as precision ATP （ acquisition, tracking, pointing） technology, high sensitive detecting and receiving technology, design technology of wide-aperture optics antenna etc. Secondly, the existing difficulties of developing ground receiving technology of satellite-to-ground optical communication are discussed. Finally, the application prospect is predicted.
