Drones are getting more stealthy, and detection technology is struggling to keep up. Scientists turned to hoverfly brains for help

ABC  

Last week, a Russian-made drone reportedly carrying an "air bomb" flew at least 560 kilometres over Croatia, Hungary and Romania — all members of NATO — entirely undetected by air defences. Key points: Drones are increasingly powerful and hard to detect, which has implications for defence, as well as commercial air travel Researchers have created a new model for detecting drones at long range by analysing how hoverflies see the world They report a 50 per cent improvement in detection range It was just the latest urgent reminder that as drones get more stealthy, drone detection technology is struggling to keep up. Eventually, they had a mathematical model of how hoverfly brains process visual signals, said Anthony Finn, an expert on sensor processing at the University of South Australia. "There is significant global interest in systems that can reliably detect drones at sufficient range to make intervention or mitigation possible," he said. Ukraine has been using drones to "great effect", a Pentagon official said last week.
