DroneTERMINATOR has been designed to protect military bases, facilities, high value assets, ceremony, meeting, demonstration areas, checkpoints and VIPs against drone and mini-UAV attacks by jamming the Remote Control Frequencies, GPS/GLONASS Satellites Navigation Frequencies and Data Link/Telemetry Frequencies simultaneously.
“Russia appears to have switched on a mobile communications jammer in Kaliningrad, a very powerful one that wasn’t aimed at Latvia, but towards Gotland, the Aland Islands,” explained Karlis Serzants, the deputy chairman of the Latvian parliament’s National Security Committee.
DRFM made it possible to mostly counter the effects of pulse compression which allowed jammers to fool the receiver into thinking that the jamming signal was the true return. It allowed jammers to do gate pull-offs or create false targets as long as those false targets weren’t closer to the radar than the jammer was.
In other words, since the main source of stealth for an LPI radar is transmitting at very little power, the fact that barrage noise jamming is power inefficient becomes much less of a problem; If you whisper, it’s easy to shout over you. The victim radar can try to remedy this by transmitting at greater power but that makes it that much easier to intercept the LPI radar. The jammer can presumably cancel out the noise he’s putting out when trying to intercept the victim radar.
Here, we show that echolocating bats rely on audiovocal feedback, instead of echo feedback, to adapt their sonar call design in response to acoustic jamming signals. Our findings demonstrate that bats, like birds and humans, not only use audiovocal feedback to fine-tune the features of their calls, but also do so on a rapid timescale.
Advertised as “directed energy”, the DroneDefender is in fact a high powered directional radio transmitter jammer, which exploits a drone’s auto-landing protocols to bring down a drone by overwhelming the controller signal with a high powered radio broadcast.
