An airborne electro-optical laser sensor designed to detect minefields has demonstrated the ability to detect simulated improvised explosive devices. The Airborne Surveillance, Target Acquisition and Minefield Detection System (ASTAMIDS) developed by Northrop Grumman, demonstrated this capability during an Army evaluation of the new system. The system was flown on the MQ-8B Fire Scout unmanned aerial system.

ASTAMIDS combines multi-spectral electro-optical sensors employing different sensing methods, including texture analysis and change detection, to spot recently buried objects suspected as mines or IEDs. In addition to its primary counter-mine and counter-IED mission ASTAMIDS also provides reconnaissance, surveillance and target acquisition capability. The system’s laser can also designate targets for laser guided munitions. Under the Army evaluation the system successfully designated targets for three Hellfire missiles.

Through a recent test series conducted in September 2010, ASTAMIDS flew 12 missions on an Army UH-1 and the Northrop Grumman owned MQ-8B unmanned vehicle. These flight tests evaluated the system’s C-IED nadir step stare, off-nadir road following and large area precision mapping capabilities.

These capabilities were supported by the new ‘ASTAMIDS Ground Exploitation Station’ (AGES), integrated with the systems’ ground control segment for the test. AGES processed streaming telemetry data obtained from the airborne sensor, enabling operators to identify target locations in near real-time.

The core of the system is the gimbaled, lightweight, multi-spectral, electro-optical and infrared imaging sensor designed to be flown on both manned and unmanned aircraft. The airborne payload weighs about 36 kg (80 pounds). Integrated with AGES processors and software, the system detects, locates and identifies ground targets, minefields, obstacles and IEDs, determines ranges to ground targets, and, as proven in the tests, designates targets for attack by laser-guided munitions.

According to the U.S. Army PM Close Combat Systems, “ASTAMIDS will give Army Brigade Combat Teams unprecedented situational awareness and target designation capabilities.” The near-real time response of the system is critical for counter-IED missions, as it provides warfighters with actionable intelligence minutes after a specific area is analyzed.

“These tests proved we’ve achieved our goal with ASTAMIDS – we can identify ground threats and deliver targeting-quality data to adjacent warfighters to destroy the threats and do that in near real time” said Dan Chang, Northrop Grumman vice president of Maritime and Tactical Systems.

The Saab group has been awarded a contract to deliver an Airborne Early Warning & Control (AEW&C) system comprising the Saab 2000 aircraft platform equipped with the ERIEYE airborne early warning radar system. The contract comprises a Saab 2000 aircraft equipped with the advanced ERIEYE radar system, ground equipment, logistics and support services, to be delivered over a period of 4.5 years. The identity of the customer has not been released but it is assumed to be one of the Gulf States. The number of aircraft to be delivered has not been released as well.

Earlier this year the UAE has ordered two smaller Erieye AEW systems based on the saab 340 platform. At the time official sources at the UAE explained the w340 is an interim solution, and that the country is still undecided on the long-term plans for its objective AEW capability, considering the Saab 2000, Boeing 737 and Northrop Grumman E-2D. Other nations in the region interested in acquiring AEW capability include Oman and Kuwait.

Another country that could be interested in such capabilities is South Africa where Saab sold the Gripen fighter aircraft and also operates local subsidiaries. In 2008 the use of Erieye was considered to bolster aerial surveillance and security during the World Cup games this year. However, the presence of such aircraft during the games was not reported. According to Saab, the Erieye airborne surveillance system in combination with the ground equipment provide a detailed picture of a situation which can be used in connection with, for example, border surveillance, rescue operations as well as in combating terrorism and organized crime.

“This contract can be seen as a further confirmation of our strong position in the world regarding not only the area of airborne surveillance but in systems integration and data fusion as well, says Håkan Buskhe,” CEO, Saab. “This surveillance system will provide the customer with improved solutions for defense and civil security.”

Saab’s ERIEYE radar is currently operated by the Swedish Air Force and Royal Thai Air Force and the UAE Air Force (on Saab 340 platforms). Brazil, Mmexico and Greece operate it on the Embraer 145 platform. The only Saab-2000 sofar is Pakistan.
