AAISAR
AISAR is a Zaragoza-based defence technology company building an AI-native radar mesh for drone detection and airspace monitoring at borders, airports and critical infrastructure. Its platform fuses a passive RF sensing mesh (400 MHz–6 GHz), which detects without transmitting and classifies more than 37 drone types from their RF fingerprints, with short-range (76–81 GHz), mid-range X-band and long-range C-band active radars. A single fusion layer and an AI digital twin tie the sensors together, and the system tracks drones from close range out to about 15 km. AISAR designs and manufactures its systems in Spain with a European supply chain free of ITAR restrictions, and its detection algorithms have been validated in operational conditions in Ukraine.
