Abstract

In order to clarify the concept of information warfare the flow of information is studied in network centric defence systems Several systems re suggested as suitable objects for further investigation in terms of information flow. This view is pedagogically useful and tends to simplify discussions about future sensor systems by introducing information flow as a common concept. The amount of available information is a convenient measure of performance if comparisons are based on the principle that optimal decisions require that all available information is considered. This rule can be proved within the context of Bayesiansk statistics and is illustrated by practical examples concerning the performance of radar systems The conclusion is that the ideas of information flow are best tested on existing sensor networks, e.g. STRIL in order to study how information flow measures the funcion. The goal is to describe the effect of jamming in quantitative terms and investigate the effect of bottle necks on information flow.
