面向卫星电子系统抗辐照能力的量化验证与评估技术

卫星电子系统抗辐照能力是影响卫星质量的关键环节之一， 对卫星抗辐照能力的验证和评估目前还停留在经验和测试阶段。 将量化验证理论方法应用到卫星抗辐照能力的验证与评估中， 在节约测试高额成本的同时，使得验证与评估更加客观合理。 本项目着重研究基于贝叶斯统计理论的量化验证理论方法与技术， 针对卫星电子系统抗辐照能力提出可行的验证方法与评估体系。 其研究成果具有重要的理论意义和很强的应用价值。 . 在前期的工作基础上， 本项目主要研究以下三部分： （1） 卫星电子系统的运行时软件故障注入试验的机制设计， 为卫星电子系统抗辐照能力的分析验证提供有效的试验数据。 （2） 基于贝叶斯统计理论的验证理论研究及工具开发，为卫星电子系统抗辐照能力的验证提供理论基础和技术支撑。（3）建立有效的卫星电子系统抗辐照能力的验证的有效方案和完善的评估体系。

It's one of the key to improve the radiation tolerance of satellite electronic system in the quality of the satellite. The verification and evaluation of satellite radiation tolerance is currently still depend on experts’ experience and testing. Applying the theory and methods of quantitative verification in studying the satellite radiation tolerance, will be free of experience as well as saving the high costs. In this project, we focus on the theory and technology of quantitative verification based on statistical methods, and propose a set of feasible verification and evaluation methods. These research results would be very important in theoretical part and practical value.. Based on the previous work, the aims of this project are as follows: (1) research and development of software fault injection experiments of satellite electronic systems, which provide effective experimental data for quantitative verification and evaluation of radiation tolerance. (2) study on the quantitative verification theory and evaluation technology based on Bayesian statistics, which provide the theoretical basis and technical support for the verification and evaluation of radiation tolerance in satellite electronic systems. (3) establishment of a more perfect verification and evaluation system, to provide effective solutions for the evaluation of radiation tolerance in satellite electronic systems.
