高强度辐射场环境下电子设备的防护与设计

Design and Protection of Electronics Product in High Intensity Radiated Fields

航空电子电气系统暴露于高强度辐射场(HIRF)环境下的误动作与工作失效等灵敏度问题,严重影响了飞行器的安全系统。因此,研究HIRF对飞机安全的影响就变得十分有必要。详细介绍了美国联邦航空局和中国民航适航部门在适航认证方面的相关标准及法规,以及设计者如何设计出符合HIRF认证标准的航空电子电气系统。

The susceptibility of aircraft electrical and electronic systems to malfunction or failure when exposed to HIRF presents a threat to aviation safety systems.Therefore,it is necessary to research the effect of HIRF to aircraft safety.This paper provides information on Airworthiness certification standards and rules of FAA and CAAC.provides information on how an engineerdesign a systems compliance with the HIRF certification standards.
