Method to Measure the Amount of Battlefield Situation Information

摘要

One of the essential issues in C4ISR is to properly measure the amount of Battlefield Situation Information (BSI), which is a key concept in the research of Situation Awareness and decision-making. BSI contains two mutually independent contributions from current status information, which describes objective state of a certain battlefield situation element at the moment, and from trends information, which expresses changes of element's state that may occur in the future. But measure the amount of BSI has not been thoroughly studied before. Here we report a novel method that precisely measures the amount of BSI on the basis of Shannon's information theory. Our method gives the first accurate quantification on current status information as well as trends information contained in BSI. Necessary conditions for two C2 nodes to reach a consensus in the process of Situation Awareness are also provided in current work.
