信号检测论在船舶了望中的应用

The Application of Signal Detection Theory in Ships' Lookout at Sea

船舶海上了望的过程就是采集和处理海上信息并判断海上危险的过程,其重点是将威胁船舶安全的有关信息检测和筛选出来。这是一种信号检测的过程。利用实验心理学中的信号检测论揭示了望信息检测中的规律,可为海上了望信息的收集和处理提供理论依据,并确立“疑险从有”的海上信息处理原则。

the process of lookout at sea is the process of collecting and processing information at sea with its focus on detecting and screening relevant information that threatens ships＇ safety. This is a process of signal detection. The analysis of the Signal Detection Theory in experimental psychology reveals the rule in detecting information during lookout at sea and provides the theoretical basis for collecting and processing lookout information at sea. The principle of ＂take it as a danger if in doubt＂ is thus established therefrom.
