From wiki:
In 2004, the IAF ordered 3 IAI Phalcon Airborne Early Warning radar system from Israel Aerospace Industries, which is considered to be the most advanced AEW&C system in the world. The air force will use 3 newly acquired Ilyushin Il-76 Phalcons as the platform for this radar. In May 2008, India appears to have ordered an additional three Phalcon radar-equipped IL-76s from Israel, pushing up the value of the deal from US$1.1 to 1.5 billion. An Indian defense delegation headed by Defense Secretary Vijay Singh, visited Israel in November 2008 to discuss the purchase of the planes and missiles from Israel Aerospace Industries (IAI). It has been reported that India has placed a follow-up order for 3 more Phalcon radar equipped IL-76 from Israel at a cost of $1.5 billion, pushing the total number to be acquired up to 6. The first Phalcons arrived in India on May 25, 2009 and are expected to be commissioned into service by 2010. IAF Air Chief said that it would take a year and a half to get each and every combat plane in IAF to link with Phalcon.

More on Phalcon Radar:

A New Generation AEW Platform: The long-range, high performance, multi-sensor PHALCON AEW introduces a new level of performance to airborne early warning, tactical surveillance of airborne and surface targets, and the gathering of signal intelligence.

Unique Integration of Sensors: The PHALCON's four sensors are : Radar, IFF, ESM/ELINT and CSM/COMINT.

A unique fusion technique continuously cross-correlates data generated by all sensors: this data is combined with an automatically initiated active search by one sensor for specific targets detected by other sensors.

Radar: A radar with conformal phased array antennas for simultaneous coverage and instantaneous focus on selected targets. The PHALCON advanced radar has several conformal phased array antennas. They are mounted on the fuselage of the aircraft and can provide up to full 360 coverage.

Advantages: Radar beams can be pointed at any direction in space at any time, with the beam?s parameters fully controlled by the radar computer. The radar employs a flexible time-space energy management technique which provides the following advanced capabilities:

· Selectable surveillance: Surveillance can be limited to the battle zone and other areas of interest. The scan rate in these selected areas is much higher.

· Optimized detection and tracking: A special mode for maneuvering and high value targets employs a high scan rate and beam shapes optimized for each target to ensure tracking performance.

· Fast track initiation and no false alarms: Verification beams sent at specific, individual, newly detected targets Track initiation is achieved in 2 to 4 seconds. eliminate false alarms.

· Extended detection range: By transmitting extra long dwells in selected sectors, an extended detection range is achieved

· High Fault Tolerance and Redundancy: The system uses distributed, solid state transmitting and receiving elements. Each element is controlled in phase and amplitude. The system continues its operation even if some of the units are faulty.

Advanced IFF employing solid state phase array technology.

The PHALCON IFF system implements interrogation, decoding, target detection and tracking using the standard modes. Azimuth measurement is carried out by monopulse processing. The IFF antennas are incorporated in the primary radar array and are coordinated with the array to avoid mutual interference. Similar antenna elements and transmit/receive modules are used for both the radar and the IFF.

Electronic Intelligence
The PHALCON's advanced ESM/ELINT system is fully integrated with the radar and other sensors, serving as one of the most important elements of the identification process. It is designed to operate in very dense signal environments, providing simultaneous 360 coverage. The system uses narrow-band and wide-band receivers to provide very high sensitivity and high probability of interception of airborne and surface emitters. High bearing accuracy for all received signals is achieved through Differential Time of Arrival (DTOA) measurements. The system also collects and analyzes ELINT data.

Communication Intelligence
Tuned in to airborne, ground and shipborne transmissions. The PHALCON's CSM/COMINT receives in UHF, VHF and HF, rapidly searching for airborne, shipborne or ground communications signals of interest. Selected radio nets can be monitored for signal activity. A DF capability locates targets. Detected signals can be assigned to monitoring receivers instantaneously. The system makes extensive use of computers to reduce the load on operators.The long-range, high performance, multi-sensor PHALCON AEW introduces a new level of performance to airborne early warning, tactical surveillance of airborne and surface targets, and the gathering of signal intelligence.
