航天器單粒子效應(yīng)的防護(hù)研究

The protection against single event effects for spacecraft

摘要: 隨著航天電子器件集成度的不斷提高，其發(fā)生單粒子效應(yīng)的風(fēng)險(xiǎn)越來越高，已經(jīng)成為影響航天器可靠性和運(yùn)行壽命的重要因素。文章首先介紹了單粒子效應(yīng)的發(fā)生機(jī)理、研究方法和研究成果，在此基礎(chǔ)上對(duì)現(xiàn)有的各種抗單粒子效應(yīng)加固技術(shù)進(jìn)行了總結(jié)，按照硬件加固技術(shù)、軟件加固技術(shù)和軌道優(yōu)化設(shè)計(jì)的思路較為系統(tǒng)地論述了單粒子效應(yīng)的防護(hù)手段。

Abstract: The risk of single event effects for spacecraft is getting higher and higher with the trend of integration of astronautic electronic devices. It has already become one of the important factors to influence the spacecraft reliability and service life. This paper first discusses the mechanism of the single event effect, and its research methods and research achievements; then reviews the existing radiation hardening technologies. The protection against single event effects is discussed in terms of hardware and software protection technologies, and the orbit optimization design.
