摘要：

为了定量地度量C4ISR系统的态势感知能力，基于Endsley的态势感知模型，分析了从察觉信息到理解信息的态势感知过程。提出了态势理解过程的三个基础经验假设，定义了随时间变化的态势差异度量。推导出反映态势变化与感知速度之间关系的微分方程，提出了态势感知能力参数的改进方法。对微分方程解的讨论，得到了与现实经验相符的结论。

Abstract:

To determine the situation awareness performance of C4ISR quantitatively, the situation awareness process, from perception to comprehension, based on Endsley’s situation awareness model. Three fundamental empirical postulations on situation understanding process are given together with a measurement on time dependent situation difference. Differential equations are established to describe the relation between the rate of situation changing and situation awareness. A modified method is given to improve the performance factor about situation awareness. The analysis results of these differential equations are in conformance with real world experience.
