数据库与实测数据融合实现对深海跃层的快速估算

摘要

Rapid assessment of ocean-cline is important to the underwater warfare. Both precision and time of assessment can decide operational efficiency. This paper puts forward a new method that constructs fuse data serial based on temperature and density delivered by real-time measured and LEVITUS database. It fused data of database by real-time data, then assessed ocean-cline by the new data serial. The result shows that the method not only can shorten the assessment time, but also can improve the precision.%海洋跃层的快速估计对于环境的态势评估具有重要意义,跃层估计的精度和估计所用时间是两个主要评估要素.基于实测的温度、密度和LEVITUS数据库中的温度、密度进行融合来对跃层进行快速估计,可通过实测数据对数据库的数据进行补充和修正,然后利用修正后的数据对跃层进行快速评估.结果表明,该方法可以大幅度地缩短跃层估计的时间和提高估计的精度.
