潜射鱼雷类型识别证据的作用机理

Effects of Evidences on Type Identification of Sub-launched Torpedo

对来袭鱼雷制导类型的识别是水面舰艇实施有针对性鱼雷防御的前提条件,证据的提取与分析则是构建鱼雷类型识别系统的基本要素。立足于战技特征层信息,从来袭鱼雷的自身特征着手提炼出4个证据,从作战海区环境着手提炼出3个证据,从战场态势信息着手提炼出6个证据,详细分析了这些证据对潜射鱼雷制导类型识别的影响原理,并对证据融合方法进行了概述。分析结果能够为客观描述证据的基本概率赋值提供重要的理论支撑,旨在有效推动潜射鱼雷类型识别系统的实用化进程。

Guidance type identification of an incoming torpedo is a premise of defending surface ship against torpedo exactly. Extracting and analyzing evidences are essential for establishing the identification system of torpedo types. In this study, four evidences are extracted from incoming torpedo information on the basis of tactical and technological characteristic information; three evidences are extracted from battlefield surrounding, and six evidences are extracted from naval battle state. The affecting mechanism of these evidences on type identification of torpedo guidance is ana- lyzed in detail, and a method of evidences fusion is discussed. This study may provide a theoretical support for objec- tively describing the basic probability assignment of evidences, and facilitate practical application of the type identifica- tion system of sub-launched torpedo.
