AWACS (Airborne Warning And Control System) a mobile, long-range radar surveillance and control centre for air defense. The system, as developed by the U.S. Air Force, is mounted in a specially modified Boeing 707 aircraft. Its main radar antenna is mounted on a turntable housed in a circular rotodome 9 m (30 feet) in diameter, elliptical in cross-section, and 1.8 m deep at its centre. The radar system can detect, track, and identify low-flying aircraft at a distance of 370 km (200 nautical miles) and high-level targets at much greater distances. It also can track maritime traffic, and it operates in any weather over any terrain. An airborne computer can assess enemy action and keep track of the location and availability of any aircraft within range.
India’s DRDO Airborne Early Warning and Control System (AEW&CS) is a project of India’s Defence Research and Development Organisation to develop an airborne early warning and control system for the Indian Air Force. It is also referred to as NETRA Airborne Early Warning and Control System (AEW&CS).
The AEWACS aircraft will have an active electronically scanned array (AESA) primary radar with IFF. The system will also have ESM (Electronic Support Measures) and CSM (Communications Support Measures) ability. Datalinks to network the AEW&CS with fighters, and ground-based control systems will also be provided, as will be the SATCOM (Satellite Communication System). The aircraft will also have a comprehensive self-defence suite. The avionics suite will be linked via a datahandling system, controlled by Mission computers.
