Paris Charles de Gaulle airport is installing a radar system developed to counter the threat of stray unmanned aerial vehicles.
The system, branded 'Gamekeeper', is being supplied by UK-based Aveillant.
Aveillant chief David Crisp says the equipment is operating in Singapore and Monaco and has been shown to detect small unmanned aerial vehicles at a range of 5km.
"We are showing the technology is ready right now that can help prevent accidents," he adds. "We shouldn't have to wait for an aircraft to hit a drone to put these measures in place."
French air navigation service DSNA will use the system as part of its 'Hologarde' strategy against drone intrusion.
