An experimental analysis of civil defense communication systems using the lower bound of KS-entropy, which is considered as an analog of the structural stealth of transmitted signals, is performed. Among the analyzed models of communication systems, models of communication systems based on chaotic signals have the highest lower bound of KS-entropy and, accordingly, the highest structural stealth. The model of a communication system with simple signals has the lowest lower bound of the KS-entropy and, accordingly, the lowest structural stealth. Model communication systems with noise-like signals has a lower bound of KS-entropy, and, correspondingly, structural stealth, much greater than the model communication systems with simple signals but less than the model of the communication system based on chaotic signals. It is established that communication systems based on chaotic signals are generally more preferable by the criterion of stealth for civil defense communication systems and can potentially find wider application in them.
