TUGA: A Polish radar for drone detection
Defence24 · · 5 min read
Poland's TUGA radar addresses a critical gap in counter-drone defense: detecting small, low-flying UAVs that conventional radars miss. Its low probability of intercept design protects operators from being targeted, a key advantage in contested environments. This system underscores the growing emphasis on passive sensing and survivability in NATO's eastern flank, where drone threats are immediate. TUGA's development signals Poland's push for sovereign defense tech and could shape future counter-UAS architectures across Europe.
The counter-drone conversation has spent a decade fixated on effectors — jammers, guns, interceptors — as though detection were a solved problem. Poland's TUGA radar is a reminder that it is not. The interesting claim here is not simply that a Polish-built set can pick up mini- and micro-drones, but that it does so while offering a low probability of detection, protecting the operator in the process. That pairing — see without being seen — reframes the small-drone problem as a sensing-survivability problem rather than a pure firepower problem, and it lands at a moment when European defense ministries are scrambling to field organic counter-UAS capability down to the maneuver unit.
The mechanics matter. Mini- and micro-drones present a genuinely hostile detection problem: small radar cross-sections, low altitudes, slow speeds that clutter conventional filters, and increasingly cheap airframes that make attrition economics brutal for the defender. Radars optimized for aircraft or even for larger unmanned systems struggle to separate a quadcopter from birds, terrain, and ground clutter at useful range. Counter-UAS sets therefore tend to trade range for resolution, leaning on Doppler discrimination, short-wavelength operation, and rapid scanning to build a track on something the size of a shoebox. TUGA's pitch sits in that class. The low-probability-of-detection element is the differentiator: a radar that emits in ways an adversary's electronic-support-measures suite struggles to characterize is harder to geolocate and target. In Ukraine, both sides have hunted counter-battery and air-surveillance radars with loitering munitions and anti-radiation effects, so a sensor that can operate closer to the forward line without advertising itself has real tactical value. It also implies a design philosophy — emissions discipline, waveform agility, perhaps passive or low-power modes — that treats the radar as a survivable node in a distributed sensing network rather than a standalone piece of equipment parked on a hill.
