New system can combat rogue drones

While combat rogue drones have become a serious threat to air-defense systems, small unmanned aircraft also pose a noticeable threat to public security authorities around the world.

New system can combat rogue drones

 

Gatwick Airport in London, Britain’s second-busiest airport, was shut down for 32 hours on Wednesday and Thursday due to a “deliberate act” of disruption by rogue drones, local police said.

Having seen opportunities in the market, Chinese engineers have devised a number of solutions to unapproved or unregulated drone flights, ranging from net-carrying missiles to laser guns. However, those methods have such limitations as immovability or short range.

Now, designers from the 207th Institute of China Aerospace Science and Industry Corp’s Second Academy are offering new apparatus to those seeking a movable and more effective counter-drone system.

The Low Airspace Defender integrates radar, an optoelectronic search instrument and a radio detector, is capable of handling all types of low-flying drones, according to Shi Chunlei, chief designer of the system at the Beijing institute, which specializes in optoelectronic technologies.

Shi said the Low Airspace Defender is China’s first fully integrated counterdrone defense system. It can detect, track, disrupt and capture unmanned aircraft operating in low airspace suspected of engagement in hostile or potentially dangerous activities. It has a designed maximum operational range of 5 kilometers, he said.

“The system can work in sophisticated environments and all weather. It uses a trio of detection and tracking methods-radar, optoelectronic scanning and radio detection-which means its detection accuracy is very high,” the designer said. “By comparison, other counterdrone solutions use one or two methods, and that means they are more likely to overlook or miss targets.”

Once the Low Airspace Defender system detects a rogue drone, it is able to continually track the target and then can use electronic jamming to disrupt its flight or directly hack into the drone’s navigation system to guide it to land in a designated area, according to Shi.
