| 摘 要： | 为了更加有效地利用大量传感器搜集的海量水面船只数据,提高护航行动的执行效率,分析了各类水面船只的时空行为特征,利用时空数据库提供的时空量算、时空聚集、时空拓扑查询等手段对可疑海盗船、护航盲区、危险商船进行了查询实验,效果显示可以利用时空数据库对未知船只进行预测分析,为护航行动提供了新的辅助决策支持手段.

| Abstract: | An effective analysis of the surface vessels situation has great significance for the commander to perceive the convoy operations situation and to make the right decision. Based on the existing query technique of Spatio-Temporal Data- Base（STDB）, a new mining method for the vast amounts of vessels data is given. A comprehensive analysis of the spatio- temporal behavior of surface vessels, and the object-oriented data model is chosen to modify it~ at the same time STDB appli- cations are introduced to discover suspicious pirates which are the biggest threat to convoy operations. |
