WebNetline’s VM system is highly flexible and resilient, providing continuous reactive coverage between 25MHz and 6GHz to counter an extensive range of threats. The system constantly scans the spectrum and responds to threats by focusing the jamming signal & power, thus overpowering, and defeating the threat. The C-Guard RJ VM enclosure concept ... As the signal is stored in memory, it can be used to create false targets both behind (reactive jamming) and ahead of (predictive jamming) the target intended for protection. Slight variations in frequency can be made to create Doppler (velocity) errors in the victim receiver as well. See more Digital Radio Frequency Memory (DRFM) is an electronic method for digitally capturing and retransmitting RF signals. DRFM systems are typically used in radar jamming, although applications in cellular communications are … See more Since a DRFM system is designed to create a false target to a radar system, this technology can be employed to perform hardware in the loop simulation. Hardware-in-the … See more A DRFM system is designed to digitize an incoming RF input signal at a frequency and bandwidth necessary to adequately represent the signal, then reconstruct that RF signal when required. The most significant aspect of DRFM is that as a digital "duplicate" of … See more • Related NATO article • DRFM Senior Design Project See more

Deep Learning-Guided Jamming for Cross-Technology Wireless Networks …

Webapproach to jamming wireless communication is to employ a reactive strategy. The reactive jam-mer stays quiet when the channel is idle, but starts transmitting a radio signal as soon as it senses activity on the channel. One advantage of a reactive jammer is that it is harder to detect. In our work [4] we implemented the above WebReinforcement learning (RL) is being considered for future SATCOM systems due to its inherent capability to self-learn the optimum decision-making policy under different scenarios. This capability enables SATCOM systems to manage their resources judiciously and mitigate jamming attacks autonomously without prior jammer type classification. WebJamming has been a major denial-of-service attack to wireless communications [1], [2]. By intentionally emitting jamming signals, adversaries can disturb network communica-tions, resulting in throughput degradation, network partition, or a complete zero connectivity scenario. Reactive jamming is one of the most effective jamming attacks. A reactive autostoel joie gemm
