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.
