Abstract
In order to evaluate the accuracy performance of the integrated navigation system, a set of evaluation index system based on device-level error is proposed in this paper, which uses a two-level fuzzy comprehensive evaluation (two-level FCE) method. Analytic hierarchy process (AHP) and entropy weighting method are used to determine the combination weights of device layer combination in the comprehensive evaluation method. Firstly, the source data is converted into percentile data by semi-ridge function. Then, the membership degree is determined by normal distribution. The characteristics of normal distribution parameters are analyzed, which is helpful for the rational selection of distribution parameters. Finally, three groups of integrated navigation systems are evaluated to verify the effectiveness of the two-level fuzzy comprehensive evaluation method. Experiment results show that the proposed method can provide good technical supports for the follow-up research.
