The performance and robustness of military command systems have been investigated by studying the information flow in a network of sensors. This kind of analysis extending from sensors to decision makers requires a detailed knowledge of uncertainties in the system but can lead to optimal decisions. The method described can be used to analyse the performance of sensor networks affected by electronic warfare and other forms of attack. One can also draw conclusions concerning the stability of different network structures. The main conclusion is that a description in terms of probability in general must include both sensors and operators. The analysis reveals that ambiguities remain a problem in a network of radar sensors and that deception is an effective method of attacking sensor networks.
