卫星装备试验鉴定数据质量评价技术及实现

Quality Evaluation Technology and Implementation of Satellite Equipment T&E Data

摘要:

以卫星试验鉴定工作开展为实际应用需求,针对卫星装备试验鉴定数据多源、多样等特点,为保证试验鉴定数据质量,提出了一种二级数据质量评价技术,重塑试验鉴定数据质量评价流程,并通过初检-数据质量筛选评价对既定卫星装备数据完整性、准确性、一致性、冗余性、有效性和及时性等阈值性指标进行首轮质量评价及筛选；在此基础上,进一步围绕卫星装备试验鉴定数据实际特性构建数据质量评价指标体系,利用多因素模糊推理下的层次分析法完成数据质量复检。在完成技术研究的基础上,以实际某型号卫星试验鉴定任务数据为例进行分析,分析结果表明所提出的技术方法切实可行,二级数据质量评价能为卫星装备性能试验、作战试验、在役考核等不同阶段的试验鉴定任务开展提供保障。

Abstract:

Taking the development of satellite test and evaluation(T E) as the practical application demand, aiming at the characteristics of multi-source and diversity of satellite equipment T E data, in order to ensure the quality of T E data, proposed a two-level data quality evaluation technology, reshapes the process of T E data quality evaluation, and evaluates the integrity, accuracy, consistency and reliability of established satellite equipment data through preliminary inspection data quality filtering evaluation. On this basis, a data quality evaluation index system is further built around the actual characteristics of satellite equipment T E data, and the data quality recheck is completed by using the analytic hierarchy process under multi factor fuzzy reasoning. On the basis of technical analysis, this paper analyzes the actual data of a certain type of satellite T E task. The analysis results show that the proposed technical method is feasible, and the two-level data quality evaluation can provide support for the different stages of satellite equipment T E tasks of performance test, combat test, in-service assessment.
