By elevating the radar above terrain obstacles, the ELM-2083A ensures persistent detection of low-flying and horizon-level threats. Unlike airborne early warning aircraft, aerostat systems provide continuous surveillance for extended periods—often exceeding a month—at lower cost and with reduced logistical burden. Presented as part of IAI’s comprehensive, multi-disciplinary defence solutions, the ELM-2083A Aerostat Early Warning Radar integrates proven technology, reliable operation, and cost efficiency to deliver a strong and enduring layer of protection for modern air defence systems.
OVERVIEW
Modern aerial threats are becoming increasingly complex, with adversaries utilizing advanced fighter jets, UAVs, cruise missiles, and other platforms designed to evade detection. These threats travel at hypersonic speeds, exploit low flight paths below the line of sight, and utilize stealth technology to reduce radar visibility. Coordinated and precise, such threats significantly reduce the reaction time for air defence forces. Events like the 2019 cruise missile attacks on energy facilities in Saudi Arabia highlight the weaknesses in current ground-based surveillance networks and emphasize the urgent need for continuous, high-level early warning solutions.

- Automatic Track-While-Scan (TWS) of multiple targets
- High probability of detection by combination of mechanical rotation with electronic steering
- Low false alarms rate
- Integrated IFF system
- Extensive Built-in-Test (BIT)
- Variety of interface options to C4I systems
Values & Benefits
IAI ELTA’s ELM-2083A Aerostat Early Warning Radar is a proven tethered system designed to meet these challenges. The system has three variations, with the strategic version featuring an aerostat at altitudes of up to 15,000 feet, providing an unobstructed view of up to hundreds of kilometres and offering 360° coverage for long-range detection and tracking of aerial targets far beyond the range of ground-based radars. The small mobile version provides point defence capabilities for strategic asset protection.
The 3D AESA solid-state radar with multibeam Doppler processing and mechanical rotation combines to offer broad coverage and accurate tracking. It can operate independently or be integrated with SIGINT (mainly ELINT), IFF, and EO/IR sensors for classification and identification. The ELM-2083A ensures seamless, continuous coverage, enhancing national air defence systems.
