First EMB-145 Rolls Out For DRDO AWACS
Indian AWACS Airborne Early Warning, Command and Control (AEWC&C) System
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.
The aircraft communicates, via its data link, with Air Defense HQ. Data from additional air defense sensors are fused to create a complete spatial picture.
The PHALCON systems can be installed on a variety of platforms, such as the Boeing 707, Boeing 767, Boeing 747, Airbus and C-130.
This system was sold to Chile in 1995, where it is designated "Condor". The Israelis began in 1993 converting a FACh Boeing 707 to carry the Phalcon airborne early warning system. Chile had repeated system problems and complained to Israel of system shortcomings.
Under the aegis of Defense Minister Yitzhak Mordechai and Defense Ministry Director General Ilan Biran, six agreements for cooperation between Israeli, American and European defense firms were signed on 15 October 1998. Under one of these agreements, IAI/ELTA Electronics Industries Ltd. and Raytheon Systems Company will cooperate on the development, production and marketing of AEWC&C systems on a world wide basis. The new project will be based on PHALCON. The two companies had teamed up to compete for tenders for AEWC&C systems for Australia, South Korea and Turkey.
Israel Aircraft Industries (IAI) was marketing its Phalcon airborne early warning (AEW) system to China in competition with the British defense firm GEC-Marconi. In 1996 Tel Aviv and Beijing signed an agreement on purchasing the Falcon radar system, which China insisted system should be fitted onto Russian Il-76 aircraft. The Phalcon's triangular radar array would be mounted on the rear quarter fuselage of the Il-76 to provide full 360 degree scan coverage. Beijing was expected to acquire several PHALCON AEW systems, and reportedly could buy at least three more [and possibly up to eight] of these systems. But in July 2000 the United States pressured Israel to back out of a $1 billion agreement to sell China four Phalcon phased-array radar systems.
The India Air Force agreed in 2004 to purchase three systems for $1.1 billion. Russia and Israel on 10 October 2004 signed a tripartite agreement to facilitate the equipping of the Indian Air Force (IAF) with the Phalcon airborne warning and control systems. The IAF plans to mount the Phalcon radar and surveillance systems from IAI on IL-76 aircraft supplied by Russia.
Airbus Military And IAI Join Forces On C295 AEW&C Programme
A Memorandum of Understanding (MOU) to this effect was signed today at the Le Bourget Airshow by IAI Corp. VP and ELTA President, Mr. Nissim Hadas, and Airbus Military CEO Mr. Domingo Ureña. With this agreement, Airbus Military will expand its mission capability to the Airborne Early Warning & Command sector, while ELTA will be expanding its AEW&C fleet to include a turboprop platform.
The C295 AEW&C has been designed to provide high quality 360 Surveillance, creating in real-time an integrated Air and Maritime Situation Picture and Electronic Order of Battle. The AEW&C Situation Picture is shared with friendly forces via Network Centric data links.
A C295 fitted with a rotodome demonstrator is conducting flight trials from Airbus Military's Seville facility since 8th June. The initial tests have shown that the aircraft is aerodynamically an excellent platform for this purpose. ELTA Systems and Airbus Military are now conducting engineering studies to integrate the mission suite, including AESA radar, among other sensors, into the aircraft. The aircraft demonstrator can be seen on the static display at the Le Bourget Airshow.
Providing a new and very cost effective solution in the so far uncovered medium size market, the C295 AEW&C is both rugged and versatile. It can be configured with the full range of AEW&C sensor and control systems, including; AEW Radar, IFF, ESM/ELINT, CSM/COMINT, Self Protection Suite (SPS), Command & Control, Multi-Mode Radar, comprehensive communication suite including Network Centric Operation (NCO) Data Networks and Satellite Links.
Airbus Military CEO, Domingo Ureña, stated: “We see a growing demand emerging for medium size early warning systems and platforms at an affordable price for both air defense and homeland security. This cooperation between ELTA Systems and Airbus Military, which combines the excellent engineering skills and experience of our two companies in their respective fields, will provide the market with a highly efficient and affordable solution, the first in this market segment”.
IAI Corp. VP and ELTA President, Nissim Hadas, referring to the mutual cooperation agreement, noted:”The emerging conflicts across the globe are emphasizing the importance of special mission fleets. We are sure that by joining forces, we will offer the market the right solution with the right technology. Airbus Military and IAI/ELTA's superior capabilities in special mission aircraft, advanced sensors and system integration enable us to provide an effective and proven solution for these growing needs.”
The new generation C295 is the ideal aircraft for military transport and civil missions such as humanitarian aid, homeland security, maritime patrol, and environmental surveillance. Thanks to its robustness and reliability, and with simple systems, this medium sized tactical airlifter provides the wide versatility and flexibility required for personnel, troop and bulky/palletized cargo transportation, casualty evacuation, communication and logistic duties, or certified air-dropping capabilities. It is fitted with both civil and military technology equipment which ensures success in demanding tactical missions, as well as growth potential for future equipment installation and compatibility with the latest civil airspace environment. The C295 is part of Airbus Military’s family of light and medium airlifters which also includes the smaller C212 and CN235 platforms.
IAI/ELTA is a front-runner in the development of airborne radar systems and in particular AESA Radar for AEW&C aircraft. IAI/ELTA’s current 3rd Generation AEW&C products, the Gulfstream G550 Conformal AEW&C and the Ilyushin IL-76 AWACS, are the leaders in their respective categories, both in terms of performance and landmark design. The newest
member of IAI/ELTA’s family of AESA Radars is a rotating dome radar combining both true 360o AESA radar and IFF in a unique low weight 4th Generation design.

India's AEW aircraft are designed to integrate information from sensors carried on a number of manned and unmanned platforms.
Russia To Develop New A-100 AWACS Plane
Russia hopes to develop a new airborne warning and control system (AWACS) plane by 2016, Air Force chief Col. Gen Alexander Zelin said on Tuesday. “We are expecting to receive the A-100 aircraft built on the basis of the IL-476 transport plane with the PS-90 engine and extended flight range,” Zelin told reporters in Moscow. The new AWACS plane will have an advanced active phase array capable of detecting and tracking airborne and land-based targets. “We will have the carrier IL-476 by 2013-2014 and should be able to build this plane by 2016,” Zelin said.
The Russian Air Force has around 20 A-50 Mainstay AWACS planes, based on the Ilyushin IL-76 transport.
The A-50 is equipped with the large Liana surveillance radar with its antenna in an over-fuselage rotodome and can control up to ten fighter aircraft for either air-to-air intercept or air-to-ground attack missions.
