Aero India 2015: IAI ELTA Showcases ISR Offerings

Showing its wide range of special mission aircraft at the latest edition of Aero India, Israel Aerospace Industries' (IAI) ELTA Systems is pursuing new orders in the ISR segment. "Selling the systems of tomorrow", deputy general manager marketing, business development and sales Avishai Izhakian explained that besides the ELI-3360 MPA offering that is available for both executive jet and turboprop aircraft such as the Bombardier Global 5000 and Dash 8 Q400, there is also the ELI-3001 Airborne Integrated Signal Intelligence System (AISIS).

Complementing the ELI-3150 SAR/GMTI Multi-Mission Airborne Reconnaissance and Surveillance System (MARS2), ELI-3001 leverages technology that is used in the SIGINT equipped Gulfstream 550s that are in operational service with the Israeli Air Force. In addition, the latter operates the Conformal AEW&C configured G550 which has recently also been ordered by Singapore, Italy as well as the US Navy that is in need of a new range monitoring aircraft. Getting back to ELI-3001 AISIS, the system is based on a multi-mission platform with the product brochure now showing a Global 5000 executive jet. This would corroborate reports of two Global 5000s for the Indian air force which have been noted in Israel being integrated with an ISR suite that has a similar outward appearance. AISIS enables long range, high endurance SIGINT missions for tactical and strategic applications, both for onboard and ground based real time and off-line analysis. Searching, intercepting, measuring, locating, analyzing, classifying and monitoring communications and radar emissions, ELI-3001 would be a tremendous asset for the Indian military as it would allow it to establish and systematically update a detailed electronic order of battle (EOB) of potential adversaries. IAI ELTA speaks of highly sensitive sensors being mounted in the AISIS platform that have a high probability of interception in the COMINT frequency range of 30 - 1200 MHz and the ELINT frequency range of 0.5 - 18 GHz. The system's automated processes include high speed scan and search within frequency bands of interest according to a preprogrammed scan regime. AISIS also features precise signal acquistion parameter measurements, and reduction by filtration as well as signal type classification. Accurate direction of arrival measurements enable a quick geo-located fix of transmitting targets. IAI ELTA's SIGINT suite also includes analysis of new, unknown signals, recording and playback possibility, and management and handling of databases using radar libraries and frequency scan tables. Fitted with an elaborate communications system including voice, data and e-mail, AISIS can be operated by onboard operators, remotely from the ground, or combined. The aircraft's cruise altitude enables a 400 kilometer line of sight (LOS) communication and interception range, according to figures provided by IAI ELTA. Cruising at approximately 0.83 Mach, mission endurance is 8 hours at 1000 kilometers from the operating base. AISIS has two-way LOS and SATCOM air-ground datalinks while radio equipment includes HF, VHF and UHF. The system's ground component including external intelligence customers can use a WAN network.

Meanwhile, IAI ELTA's ELW-2090 AEW&C package builds on experience that was first gained when upgrading Boeing 707s for Chile with conformal radar arrays, with this system being known as the Phalcon. ELW-2090 is IAI ELTA's third generation AEW&C system, installed on the Ilyushin Il-76. Used for wide area persistent radar coverage, the Il-76 based solution is operated by India where it will be supplemented by the new indigineous AEW&C system based on the Embraer EMB145 platform that is about to enter service. Fitted with three AESA L-band radar arrays in a massive dome on top of the Il-76 transport aircraft, ELW-2090 offers 360 degree coverage with accurate 3D tracks, low false alarm rates, ECCM and programmable search and track regimes. IAI ELTA's AEW&C solution also features IFF, ESM/ELINT and CSM/COMINT capabilities together with an elaborate electronic warfare self protection system. Up to 11 interchangeable operator work stations can be accommodated that are part of an isolated enclosure that was introduced to cope with the noise levels caused by the aircraft's engines, Izhakian explains. HF, VHF, UHF radios are part of the overall package that also features SATCOM, VOIP, secure voice, integrated intercom and secure LOS datalink.

Available for Beechcraft King Air variants (200, 300, 350ER), RUAG Do-228, Cessna 208B Grand Caravan, PZL M28, Fokker 50 and others, the ELI-3120 Compact Multi-Mission ISR Aircraft is a multi-INT system. As there continues to be a growing market for manned ISR platforms for COIN and homeland security operations that can accommodate both sensors and onboard analysis capability, IAI ELTA has made sure that the ELI-3120 system can be used for a wide range of missions. These include border surveillance, counter narcotics, ground situational awareness picture, intelligence gathering (SIGINT), or even maritime surveillance, search and rescue and fire spotting. A scalable system, the suite would typically comprise a maritime surveillance or SAR/GMTI radar, and/or COMINT, DF sensors for wide area search. A high definition EO/IR pod would be used for closer scrutiny of possible targets that are found. Operator work stations in the cabin enable monitoring and analysis while LOS and SATCOM datalinks ensure air-ground connectivity. Also included are an onboard recording system, ground based preflight mission planning and post-mission analysis stations. EWSP, ELINT, VHF/UHF COMJAM capability would be optional just as SATCOM BLOS communications and tactical communication with deployed ground troops.
