| Abstract: |
| This paper proposes the principles and methods for selecting the health characte
rization parameters based on Failure Mode, Effects and Criticality Analysis(FMEC
A),Fault Tree Analysis(FTA) and historical cases.At the same
time，it discusses the method and application of the health characterizat
ion parameters based on Hidden Markov Model(HMM) and Bayes. Considering the inte
grated RF channel a
rchitecture in airborne avionic system, this paper analyzes the health influence
on RF channel by means of the built model and selected characterization paramet
ers. The results are important for the technology research of advanced fighter
health management. |
