Multi-source data fusion and situation generation method and system

The invention relates to a multi-source data fusion and situation generation method and system, and the method comprises the steps: obtaining original target data of a plurality of intelligence sources, carrying out the analysis and preprocessing, and building an original target library; performing data association by adopting a fuzzy decision association strategy; carrying out data fusion processing by adopting a D-S evidence theory algorithm, and establishing a fusion database; generating a target track according to a data fusion processing result, and establishing a target track library; performing target situation estimation and target threat assessment according to the generation result of the target track, outputting a situation result, and establishing an intelligence situation library; and managing and displaying the original target data, the fusion data, the target track data and the situation data. According to the method, the fuzzy decision association strategy is adopted for data association, and
