In just a few years, drones have transformed from a hobbyist affair to an all-together cultural wonder. This small wonder can, however, cause a lot of havoc. On January 21, fiights in and out of an airport near New York were suspended temporarily because of drone sighting. Heathrow, London’s biggest airport, had to be shut briefly for the same reason a few days earlier. Close drone encounters are being increasingly reported by airline pilots. On December 15, a Boeing 737 plane managed to land safely after its wing was severely damaged in a collision with a drone. Along with that, drones are being misused in assassination attempts, to attack military bases, and to smuggle goods across countries and drugs into prisons.
All such incidences have increased concern of the authorities. They find that the threat from attacks by rogue drones is continuously escalating in the absence of proper methods to control these drones. Signal jamming, the most popular method, if used in areas such as the airport, is prone to damaging other sensitive radio and navigation equipment, and the instruments on aircraft. Firing bullets or lasers to bring down a drone can be dangerous near a commercial airport or in public areas. Measures such as educating the drone pilots, imposing tough penalties, and installing features to prevent entry into restricted areas have helped to some extent but have not provided a comprehensive solution. Therefore, better technology is required to combat such rogue drones.
The bright side is that technology is improving. Recently, a big Spanish company announced that it has completed extensive testing of an anti-drone system called ARMS in “dangerous” places. It uses a sensitive radar to identify a drone and then uses infrared cameras to confirm the type of the identified drone. It further determines the type of signals being used by the drone. This process of identification allows ARMS to attempt a carefully targeted form of jamming. This system can thus disable either a single drone or a swarm of them, without affecting any other electronic equipment nearby. Such systems can also be made portable so that they can be used at special events. It can be expected that they will become increasingly sophisticated, and in a few years, we will have complete control over the small wonder.
