Advances in Drone Detection and Countermeasures

In Aalborg, Denmark, MyDefence, a company specializing in anti-drone technology, has seen a surge in demand for its equipment, which jams drone communications to force controlled landings. Initially serving military clients, including NATO and Ukraine, the company now attracts civilian customers like critical infrastructure firms. The technology disrupts drone-pilot connections using radio signals and can block GPS signals. Detection remains a challenge due to drones’ small size and materials like plastic, which are hard to spot on traditional radar. Solutions include acoustic sensors, high-resolution cameras, and advanced tactical radars. The war in Ukraine has driven innovations, with drones now using fibre optic cables or autonomous navigation to evade jamming. Companies like Nordic Air Defence are developing low-cost interceptors, such as 3D-printed missile-like devices, to physically disable drones. Cost is a critical issue, as defending against cheap drones with expensive missiles is unsustainable. Incidents of drones breaching airspace in countries like Poland, Romania, and Germany highlight growing security concerns. Alternative methods, like nets, lasers, and hacking for controlled landings, are being explored, alongside calls for drone traffic management systems to distinguish authorized drones. Investments in anti-drone systems, like Sweden’s $365m plan, reflect the urgency of addressing this evolving threat.
