摘　　要：介绍了数据融合技术的基本概念及工作原理,并以某型水雷高速弹道测试系统中2台捷联惯性测量装置的数据为例,提出了加权平均数据融合法在水下弹道测试中的应用。对某型高速弹道测试系统中的多源数据进行了融合与分析,结果表明:该数据融合方法可有效平滑数据,减小数据间断或跳变等不良影响,提高多信源、大时空覆盖范围的弹道测量数据的可信度。This paper introduces the basic concept and principle of data fusion technology,and takes the data of two inertial measurement units in a high-speed ballistic testing system of a mine as an example.The application of weighted average data fusion method in underwater ballistic testing is described.Multi-source data from the high-speed ballistic testing system is fused and analyzed,and the results show that this data fusion method can smooth the data effectively,reduce data discontinuity or jump and other adverse effects,and improve the confidence level of ballistic measurements with multi-source,large spatial and temporal coverage.
