摘要：This paper introduces a radiation hardness
evaluation method for complex system based on the
combination of simulation and test data. The method consists of
three major steps including pre-QMU analysis, initial QMU
analysis and refined QMU analysis, which is an extension of
classical quantification of margins and uncertainties. The
rigorous performance evaluation results can be obtained
through model calibration, uncertainty propagation, and the
combination of simulation and test data based on CoM
inequality. Compared with the pure model-based quantitative
evaluation and the qualitative engineering evaluation, the
method ensures a 100% confidence of the certification when the
system performance is certified. To verify the effectiveness, the
method is applied to the radiation hardness evaluation of a
satellite power system. The test data is collected through a small
amount of in-orbit data, and the engineering model is used as
the simulation model. The result shows that the method for
system performance evaluation is valuable in engineering.
Finally, the paper looks forward to some issues needing further
research.
