Technology Of Signal Scrambling Which Freezes Drones In Middle Air

The new Anti UAV Defense System (AUDS) was developed by three tech companies in the United Kingdom. It has a radar detection component, advanced tracking capabilities and a sneaky little onboard device that keeps drones at bay.


A new device that can detect, target and deter commercial drones could be used to keep the flying robots away from areas where they aren’t wanted, like government properties, airports or your own backyard.

Drone operators typically communicate with, and direct, the aerial bots using radio signals. Enter AUDS, which uses a drone’s communication system against it.

Using directional antennas pointed at the drone, AUDS sends the unmanned aerial vehicle (UAV) radio signals that interfere with the radio signals coming from the remote operator. When the drone picks up AUDS’ signals, it freezes unsure of where to fly.

Rather than melting drones in midair like Boeing’s new Compact Laser Weapons System, AUDS shoots the flying vehicles with something that does not destroy them radio waves.

Although drones can be amazingly useful they can help schmoozers keep tabs on secured areas and help farmers survey their crops more quickly these flying robots have stirred up quite a few problems in recent months.

AUDS can spot a drone from about 5 miles away. After zeroing in on its target, it uses video and thermal imaging software to keep the flying vehicle in its sight. Once the drone gets close enough to the anti-drone system, it is game over for the drone.

AUDS system does not promise to help locate errant drone operators, it’d be used to keep drones away from restricted areas altogether. The radio jamming technology aboard AUDS does not scramble signals from commercial or military aircraft, which use ciphered signals, so it might be safe to use near airports.

The new anti drone system has been tested in the United Kingdom, the United States and France, but there is no word yet on when or where this drone-freezing technology could be used in these countries.
