<p>Three UK firms have created a new technique that uses radio beams to freeze drones in mid-flight to prevent them from entering sensitive areas.<br /><br /></p>.<p>The Anti-UAV Defense System (Auds) covertly jams a drone's signal, making it unresponsive.<br />A drone flying in sensitive airspace can be detected by the Auds radar and then sighted via a camera equipped with thermal imaging capabilities so that it can be targeted visually.<br /><br />Then, a high-powered radio signal can be focused on the drone - essentially overriding the connection to whoever is operating it, the BBC reported.<br /><br />The Auds operator can choose to freeze the drone just for a short time - to convince its owner that there's something wrong with it - or for a longer period, until its battery dies and it crashes.<br /><br />The whole process takes as little as 25 seconds, according to Paul Taylor of Enterprise Control Systems, which developed the product along with Blighter Surveillance Systems and Chess Dynamics.<br /><br />"It's a radio signal. There are a number of frequency bands that are used by all of the manufacturers," explained Taylor.<br /><br />"We transmit into those frequencies in the direction of the UAV using a directional antenna," he told the BBC.<br /><br />"There's quite a lot of radio power on to the UAV - so much so that it can only hear our Auds signal," he said.</p>
