Tactical communication network countermeasure method based on signal recognition and network reconnaissance

Abstract

The invention provides a tactical communication network countermeasure method based on signal recognition and network reconnaissance. The method comprises the steps of tactical communication network comprehensive situation awareness, tactical communication target attribute recognition based on time-frequency-space characteristics, detection of the specific tactical communication target based on synchronization characteristics, time-division multi-target jamming based on network key information and tactical communication network countermeasure based on synchronization decoy. The core of the method is to recognize the target attributes, locate the network node, analyze the traffic type and perform statistics of the traffic volume by using the signal time-frequency spatial domain characteristic and network characteristic information so as to realize communication signal recognition and network comprehensive situation analysis under the complex battlefield electromagnetic environment. Time-sharing jamming is performed by using the sparsity of the network key information for different target networks to improve the multi-target jamming capacity, and synchronization decoy jamming is performed by using the vulnerability of the synchronization mechanism to effectively counter the ad hoc encrypted communication network characterized by multi-hop routing and forwarding and high-speed frequency hopping.

AI Technical Summary

Problems solved by technology

In addition, regardless of frequency division or time division, traditional jamming methods are difficult to be effective in the face of ad hoc self-organizing communication networks represented by the tactical Internet. If the link is interrupted, the enemy and the communication parties can still forward data packets through other network nodes to achieve normal communication
