摘要: 本文定义了航空电子设备大气中子单粒子效应(NSEE)硬失效、硬错误与软错误等大气中子辐射可靠性表征参数,提出了一套航空电子设备抗大气中子单粒子效应危害能力的试验评价方法,包括试验应力终止条件与起始条件的确定方法、MNSEE预估方法、试验程序、试验评价方法等,并通过某航空用卫星导航接收机试验案例证明了该方法在工程应用中的可操作性与有效性,通过掌握数字信号处理(DSP)、静态随机存储器(SRAM)、现场可编程门阵列(FPGA)的NSEE敏感特性,可为航空用卫星导航接收机NSEE危害防控提供针对性的技术支持.本文为我国航空电子产品大气中子单粒子效应试验评价奠定了理论与应用基础,同时也为其他电子信息产品在大气中子单粒子效应试验评价方面提供了重要依据和参考.

Abstract: The atmospheric neutron radiation reliability parameters, such as hard failure, hard error and soft error for avionics neutron single event effect (NSEE) were defined. A set of testing and evaluation method to demonstrate the avionics NSEE-resistance capability was presented and verified by a case study on some aircraft satellite navigation receiver NSEE testing and evaluation. The testing and evaluation method included test stress determination method on ending condition and starting condition, MNSEE prediction method, test procedures, testing and evaluation method, etc. This case study verifies that the NSEE testing and evaluation method for avionics is practical, operational and effective in the engineering application. The NSEE sensitivity features of DSP, SRAM and FPGA in aircraft satellite navigation receiver may provide pinpointed technical support for NSEE mitigation and protection for the related NSEE failure. The theoretical and application foundation is paved for atmospheric neutron single event effects testing and evaluation for avionics in China. In the meantime, it provides important and valuable reference for the atmospheric NSEE testing and evaluation for other electronic and information products in China.

Key words: atmospheric neutron single event effect (NSEE), NSEE testing and evaluation method, MNSEE prediction method, radiation reliability, aircraft satellite navigation receiver, hard failure, hard error, soft error
