| 摘 要: 随着临近空间飞行器的发展，空空导弹作战空域也向超高空域拓展，因此在空空导弹设计时需要考虑高 能粒子引起的计算机系统瞬时故障。本文从软件防护的角度出发，针对该故障提出了一种基于冗余备份及校验和的软件 数据流加固方法。试验表明，该算法对单粒子翻转引起的瞬态故障具有良好的防护性，具有通用性好、易移植等优点。 关键词：飞控软件；软故障；单粒子翻转；软件容错；数据流错误恢复 |

| Abstract: With the development of near-space vehicle,the combat airspace of air-to-air missile is also extended to the ultra-high airspace.Therefore the design of air-to-air missile needs to consider the transient fault of the computer system caused by high-energy particles.From the point of software protection,this paper proposes a software data-flow reinforcement method based on redundant backup and checksum.The experimental results show that the algorithm has the advantages of good protection against transient faults caused by single event upset,and has the advantages of good universality and easy transplantation. |
