摘　　要：针对体系化外弹道试验测控模式和海量原始数据深入挖掘需求,提出一种基于Hermite函数来约束外弹道参数的多源异类测元数据融合方法,简称EMBET融合方法。对多源异类测元数据分别采用常规融合方法和Hermite融合方法进行仿真计算分析。结果表明:Hermite融合方法在多体制测控模式下外弹道数据融合领域具有更高的定位精度、更敏感的系统误差探查能力和实用性更强的特点。For systematic exterior ballistic measurement and control mode and the need of deep analysis of massive raw data,a data fusion method with multi-source heterogeneous measurement elements was proposed based on exterior ballistic parameter restricted by Hermite function,which was called Hermite fusion method for short.The multi-source heterogeneous measurement elements were simulated and calculated by applying routine fusion method and Hermite fusion method respectively.The result shows that,in exterior ballistic data fusion field with multi system measurement and control mode,the Hermite fusion method has high positioning accuracy,sensitive system error detecting ability and stronger practicability.
