Israel Aircraft Industries (IAI) developed its Phalcon system for Israeli defence forces and for export. Airborne Early Warning, Command and Control (AEWC&C) systems play a major role on the modern battlefield by providing realtime intelligence command and control needed to achieve and maintain air superiority over the combat area, and to enable surveillance of borders in peacetime. The AWE&C phased array radar replaces the conventional rotodome radar. It is mounted either on the aircraft fuselage, or on top of the aircraft inside a stationary dome, providing full 360° coverage. This electronically steered beam radar, offers a tremendous advantage over mechanical rotating antenna, as it supports the tracking high maneuvering targets. The radar can detect even low flying objects from distances of hundreds of kilometers, day and night, under all weather conditions. Verification beams sent at specific, individual, newly detected targets, eliminate false alarms. Moreover, track initiation is achieved in 2 to 4 seconds as compared to 20 to 40 seconds with a rotodome radar. This system had been sold to Chile, where it is designated as "Condor.
In September 2000 it was reported that Rosvoorouzhenie, Russia's arms-exporting company, had entered negotiations with China to lease a pair of A-50 aircraft, as a replacement for the Israeli Phalcon. The terms of the lease to China were expected to be finalized as soon as late November or December 2000.
In early April 2000 Russia reached preliminary agreement to lease two A-50 aircraft to the Indian Air Force to step up its aerial surveillance on the border with Pakistan. India conducted trials of the A50 in July 2000, and the results were reportedly satisfactory. Beriev was to produce three A-50E AEW aircraft for India with IAI of Israel providing the aircraft's electronic systems. The A-50E airborne early warning and contol aircraft is intended to perform the following missions: detection, tracking and IFF determination of the air and surface targets, surveilance, command, control and communication functions for both commands posts of automatic control systems, guidance of fighters to air targets and attack aviation to serface targets.
The Israeli-made Phalcon radar would extend the range of the Indian air force, enabling very long-range identification of targets and control over the weapons aimed at them. There is no American equipment on the Russian planes.
In mid-2003 the US approved the sale of the Israeli produced Phalcon airborne radar system to India. In October 2003 Russia, India and Israel signed an agreement for supply to India 3 A-50 aircraft (based on Ilyushin-76 airplane) for long-distance radiolocation control, detection and guidance. At the request of the Indian party, the aircraft will be equipped with low-noise and fuel-efficient PS-90A-76 engines instead of usually provided D-30KP engines. A part of the revenue obtained from the deal will be received by the manufacturer of the PS-90A-76 engines - Perm Engine Company.
On 25 September 2007
ShipbuildingRu reported that the first of the three A-50EI AWACS planes intended for the delivery to India, would be sent to Israel before the end of 2007 for installing the Falcon radar. General director of the Taganrog Beriev aviation scientific and technical complex Victor Kobzev stated that the assembly works were at the final stage. On 08 September 2008 Russia's state arms exporter, Rosoboronexport, said that Russian companies would provide after-sale services for three A-50EI AEW aircraft that have been sold to India. The export version is fitted with the Israeli-made Phalcon radar system. The first aircraft was scheduled to arrive in 2007-08 but delivery has been delayed.
SPECIFICATIONS
The Phalcon AEW&C aircraft is based on four sensors: phased-array radar, phased-array IFF, ESM/ELINT and CSM/COMINT. A unique fusion technology continuously cross-relates the data gathered by all sensors. When one of the sensors reports a detection, the system automatically initiates an active search of the complementary sensors.
- The AWE&C phased array radar replaces the conventional rotodome radar. It is mounted either on the aircraft fuselage or on top of the aircraft inside a stationary dome, providing full 360° coverage. This electronically steered beam radar delivers a tremendous advantage over mechanical rotating antenna, as it supports the tracking a high maneuvering targets. The radar can detect even low flying objects from distances of hundreds of kilometers, day and night, under all weather conditions. Verification beams sent at specific, individual, newly detected targets eliminate false alarms. Moreover, track initiation is achieved in 2 to 4 seconds as compared to 20 to 40 seconds with a rotodome radar.
- The IFF system employs solid state phased array technology to perform interrogation, decoding, target detection and tracking. A monopulse technique is used to implement azimuth measurement. The IFF data is automatically correlated with the phased array radar.
- The ESM/ELINT system receives, analyzes and locates radar signals, covering 360o. It combines high sensitivity with high probability of intercept, and achieves excellent accuracy in bearing measurement. The system uses narrow-band super-heterodyne receivers and wide-band instantaneous frequency measurement (IFM) techniques to provide very high accuracy and probability of intercept of airborne and surface emitters. Very high bearing accuracy for all received signals is achieved through Differential Time of Arrival (DTOA) measurements. The system also collects and analyzes ELINT data.
- 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.
