Multiple data sources fusion method for effectiveness evaluation of ship-borne TT&C system

A novel method which synthesizes the expert experiences and test data to evaluate the effectiveness of space tracking, telemetry and command (TT&C) system is proposed. The data sources include qualitative indexes and quantitative indexes. Unified expression of heterogeneous data is realized by belief map as data description form. Taking optimization and reduction to the indexes system, using belief map as data description form, using extensive Bayesian algorithm to fuse data from multiple sources, the fusion evaluation framework is given. Taking effectiveness evaluation of USB TT&C system as an example, this paper demonstrates that the data fusion method has a certain practicability and validity, which can effectively improve the reliability and credibility of evaluation results.
