Polish-Ukrainian Startup Develops Radar System to Detect Low-Flying and Fiber-Optic Guided Drones

Polish-Ukrainian startup Molfar Defence is working on a next-generation radar system aimed at detecting small drones operating at low altitudes, a category of threats that has become increasingly challenging for air defense and counter-UAS operators during the war in Ukraine. According to the company, the system is being designed to identify drones flying close to the ground, including fiber-optic controlled platforms that cannot be disrupted through conventional electronic warfare techniques. 

The development effort is focused on improving detection performance against targets that often evade traditional radar coverage due to their size, flight profile, and limited electromagnetic signature. Fiber-optic drones have emerged as a growing concern because they maintain a physical connection to operators through long cable links, allowing them to operate without relying on radio-frequency communications that can be jammed or intercepted. 

Molfar Defence is positioning the radar as part of a broader counter-drone architecture intended to support frontline units and critical infrastructure protection. The company operates at the intersection of Polish and Ukrainian defense technology ecosystems, drawing on operational lessons generated by Ukraine's ongoing efforts to counter evolving Russian drone tactics. 

The project comes amid rising investment across Europe in drone detection and airspace monitoring technologies. NATO members and EU states have accelerated efforts to strengthen defenses against low-cost unmanned systems following repeated drone incidents near critical infrastructure and along the Alliance's eastern flank. Analysts increasingly view advanced sensors, including specialized radar systems, as a key component of future layered air defense networks. 

For Poland, the initiative also aligns with broader efforts to expand domestic drone and counter-drone capabilities through cooperation with Ukrainian industry. Warsaw has increasingly emphasized the importance of integrating battlefield-tested Ukrainian expertise into its defense modernization and industrial development programs. 

If successfully fielded, Molfar Defence's radar could provide military and security operators with an additional tool for detecting and tracking small unmanned aircraft that have proven difficult to counter using existing surveillance and electronic warfare systems.
