Concurrent Multi-Target Communication Jamming in a Single-Channel Jammer Scenario

The mobile deployment of jamming devices involves limited resources that require efficient jamming. To address this, we present novel research results in the field of jamming multiple targets concurrently utilizing only a single jamming channel. By using multi-objective optimization (MOO) and multi-criteria decision making (MCDA) techniques within an experimental approach, we optimize sweep-based jamming signals and approximate the effective jamming range for a real-world UAV scenario. In this context, we observed the sweep-based jamming signals presented to be superior to conventional sweep signals. For specific scenarios, we found that by exploiting the vulnerabilities of individual targets, concurrent jamming is possible with only minor deterioration in jamming efficiency compared to the single-target application. In addition, we present widely applicable techniques to enable robust decision-making for the hands-on process of selecting jamming signal parameterizations. Due to the hardware-in-the-Ioop architecture of our experimental approach, the presented technology is future proof, paving the way to discover vulnerabilities of yet unknown targets to increase protection from these threats.
