Full-Duplex Jamming and Interception Analysis of UAV-Based Intrusion Links

Abstract

This letter addresses the evaluation of the performance of a full-duplex (FD) jammer and intercepting node, where the FD node attempts to disrupt the communication link of an intruding unmanned aerial vehicle (UAV). The FD node's performance is evaluated by deriving an analytical expression of the probability of successfully interrupting the communication link between the UAV node and its control source (CS). Moreover, the analysis takes into account the channel characteristics between the interacting nodes. Simulations were conducted to examine the dynamics of the proposed system model by varying different key parameters. The conducted simulations verify the accuracy of our derived expressions, and the results highlight the importance of having low residual self-interference power in order to successfully intercept the communication link between the UAV node and its control source.
