WebThe jamming system is intended as a mobile system which is installed in the vehicle. It is equipped with the Omni-directional antennas that are part of the system. The output power of the jammer is up to 740 W. The jamming system is easily controlled and the failures are easily diagnosed. It is controlled on the front panel. WebMay 28, 2024 · This kind of jammer attacks the channel whenever it detects transmission from legitimate radios. With recent advances in self-interference suppression or in-band full-duplex radios, a reactive jammer can jam and simultaneously sense/discern/detect the legitimate transmission. Such a jammer is referred to as a smart reactive jammer. 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.
