Aerostat Early Warning System

The ENA-2083 is an operationally proven tethered aerostat-borne, 3-D multiple beam, Doppler radar system providing accurate longrange early warning and air defense capabilities. Deployed at high altitude, the system’s advanced Active Electronically Scanning Array (AESA), L-Band radar is able to detect and track multiple targets including aircraft, cruise missiles, loitering munition and other low flying threats, well beyond the range of ground based radars. The robust system offers persistent operation up to 30 days as well as low operating costs.

The system can be further enhanced with the addition of SIGINT sensors, IFF, and EO/IR improving classification, identification and target discrimination. Moreover, the system can act as a communication relay extending LOS communication networks. The complete solution is managed by a Command and Control center and can interface with other C4I systems.
