摘　　要：高能带电粒子造成的单粒子翻转是影响卫星光通信系统性能的重要因素,给出了单粒子翻转的物理机制及主要研究方法。利用OMERE 3.4软件对星载CMOS 2164器件进行了单粒子翻转率计算,结果表明,通过对轨道倾角和轨道高度的优化设计可以有效减小卫星光通信系统中电子器件的单粒子翻转率。为了有效克服单粒子辐射效应,除了简单的增加屏蔽层厚度等防护方法外,还应考虑通过电子器件的选择来提高抗辐射性能。High energy particle induced single event upset（SEU） is one of the most important factors affecting the laser satellite communication system.Its physical mechanism and main research methods are given out.The OMERE 3.4 software is used to calculate the SEU ratio of satellite-borne CMOS 2164 device.The calculation results have proved that optimizations of the orbit altitude and orbit inclination could effectively decrease the SEU ratio of electronic device in satellite optical communication system.To further reduce the single event effect,besides some simple protection methods like enhancing the shield,the device selection should be considered to improve the anti-radiation performance.
