摘　　要：为了对数据融合系统性能进行综合评估,建立了相对完备的分布式融合系统性能指标体系.提出了一种基于粗糙集的数据融合系统灰色评估模型,通过引入粗糙集理论,对指标进行约简并确定权值,减少了主观因素的影响,提高了评估的公平性.通过算例证明了模型的可行性和可靠性,为数据融合系统的开发、论证和实际使用提供了科学的理论决策依据.In order to evaluate the overall performance of data fusion system,an approximately complete set of criterions is established for the distributed kind. An evaluation model of grey relation analysis based on rough set theory is proposed,which by means of applying rough set theory reduce redundant attributes and determine criterion weight values,thus resulting in less subjectivity and more objective evaluation results. The feasibility and credibility of the model is proved by an example. It provides a scientific decision foundation theoretically for development,demonstration and practical application of the data fusion system.
