不同信息源条件下的目标初始位置分布预测

Forecast for underwater target′s initial position distribution based on different information source

为使目标的初始位置分布假设更为合理,根据海上搜索编队所携带探测器材的特点,分析了搜索编队执行搜索任务时可能获得的多种信息源,并将之划分为精确信息源、模糊信息源和推测信息源3类,分别阐述了搜索编队在获得3种不同信息源情况下目标初始位置分布的预测方法.通过实例仿真,给出了海上搜索编队在获得不同信息源情况下的后续搜索行动建议,该方法可作为对海上搜索编队的搜索战法研究的参考.

In order to make the hypothetical of target＇s initial position distribution more reasonable, according to the properties of sea search fleet＇s detective equipments, firstly, kinds of information sources which may be obtained during search action by sea search fleet were analyzed. These information sources could be classified into three kinds： precise information sources, fuzzy information sources and hypothetical information sources. Secondly, the forecast method for target＇s initial position distribution based on these three kinds of information sources was put forward. Finally, the suggestion about subsequent search action during different information source was provided, which can be used as a reference for the cooperative tactics of sea search fleet.
