国外微放电设计与测试标准研究进展

Research progress of abroad multipactor design and test standard

微放电是航天器大功率微波部件不可避免的问题,为了满足航天器有效载荷发展任务需求,近年来航天器微波部件制造工艺、技术水平都得到大幅度提升,相应的验证测试也变得更为细致严谨,美国政府及航天工业联合建立了微放电检测标准,欧洲空间标准化组织修订其微放电检测标准,我国也建立了相关微放电检测标准。文章介绍了国外微放电设计与测试标准研究进展,主要介绍了与我国检测标准不同的部分,包括美国微放电检测标准中的最低微放电准则、微波部件分类及分析方法,欧洲微放电检测标准中的微波部件分类与微放电考核方法、多载波微放电测试方法,以期为国内微放电检测研究提供参考。

Multipactor is an inevitable problem of spacecraft high-power microwave components.In order to meet the task requirements of spacecraft payload development,manufacturing process,technology level of microwave components have improved greatly in recent years,while the corresponding verification test have become more detailed and rigorous.American authors throughout the government and the aerospace established multipactor test criterion,ECSS revised its multipactor test standard,and China also established relevant multipactor test standards.This paper introduces the foreign multipactor design and test research progress,introduces mainly the different parts including the minimum multipactor criteria,microwave component classification and analysis method,as well as european multipactor test standard of microwave component classification and multipactor assessment method,multi-carrier multipactor test method,providing reference for domestic multipactor detection research.
