FLIR SYSTEMS Continued from page 5 MODIS sea-surface temperatures are required to model air-sea temperature interactions that affect climate and weather and correct radar tracking of incoming missiles threatening our ships at sea. Its estimates of aerosol levels and cloud cover contribute to global weather and climate prediction. Its vegetation assessments support global and seasonal crop forecasting. Its dust storm warnings support tactical military operations. The spectral capability of MODIS is the key to its ability to detect dust storms and provide key reports to military planners regarding the density, position, size, trajectory and visibility of these sand blizzards. Special spectral channels in the visible, nearinfrared and even longer wavelengths in the infrared, sensitive to temperature, allow MODIS to segregate land, ocean, clouds and dust in the same picture. MODIS has proven to be not only a successful tool to support scientific environmental studies — the basic mission for which it was originally designed — but also a necessary adjunct to civil weather forecasting and military operations worldwide (see Figure 1 on page 5). In OEF and OIF conflicts that continue to make headlines, desert dust storms are the bane of infantry and airmen. MODIS is a key combat ally as well as an essential tool for continued NASA environmental research. Global Hawk Integrated Sensor Suite and Ground Segment With its unmatched sensor technology and sophisticated ground support systems, the Global Hawk unmanned aerial vehicle (UAV) offers a dramatic warfighting advantage. Raytheon developed the electronic sensors, radar and ground-based elements that allow Global Hawk to excel at providing critical ISR data to military field commands. Day or night, on land or at sea, and in all kinds of weather, the Raytheon Integrated Sensor Suite (ISS) on the air vehicle (Figure 2) pinpoints stationary or moving targets with unparalleled accuracy. It transmits imagery and position information instantaneously from 65,000 feet with dramatic clarity, empowering warfighters to respond quickly and decisively. 6 2005 ISSUE 1 The Raytheon-built ISS enables Global Hawk to scan large geographic areas and produce outstanding high-resolution reconnaissance imagery. In just 24 hours, Global Hawk’s wide-area search mode can cover 40,000-square nautical miles with 1-meter resolution; while in spot target mode, the sensors can search 1,900 2 km x 2 km spots with 0.33-meter resolution. To provide Global Hawk with its broad sensing, night vision and radar-detection capabilities, ISS combines a cloud-penetrating synthetic aperture radar antenna with a ground moving target indicator, a high-resolution EO digital camera and an IR sensor. A common signal processor, acting as an airborne supercomputer, ensures that all elements work together. Figure 2.

2nd-Generation FLIR Moving Ground Forces’ Mission Operability Beyond Traditional Boundaries In the first Gulf War, “We own the night” became the catch phrase of the day. That war was fought with first-generation thermal sensors built circa 1980. Second-generation forward-looking infrared (FLIR) sensors for ground combat made their large-number debut in Operation Enduring Freedom (OEF) in Afghanistan and Operation Iraqi Freedom (OIF) in Iraq. Both first- and second-generation systems have been credited with being a “force multiplier” and were enabled by Raytheon-developed technology. The superior performance of the secondgeneration FLIR allowed our warfighters to expand, and even improvise, on missions with this powerful new capability. Second-generation FLIR was born out of lessons learned from the first Gulf War. Due to the disparate performance of the earlier systems, the stated goal was for all armored vehicles to have a “common view” of the battlefield. A second goal was to reduce system cost by standardizing components, thus taking advantage of the economies of scale. Today, Raytheon Network Centric Systems (NCS) is the leader in second-generation electro-optical (EO)-based gun and missile fire control systems and surveillance systems, having delivered thousands of systems to date. NCS provides the EO sensor for the Improved Target Acquisition System (ITAS) used by the 82nd and 101st Airborne Divisions. The Scouts of the 3rd Infantry Division (ID) have our Long-Range FLIR SYSTEMS (CONTINUED) architecture, this advanced system provides long-range surveillance, target acquisition, tracking, rangefinding and laser designation for semi-active laser missiles and for all tri-service and NATO laser-guided munitions. With proven combat experience, the MTS and variants are available to support domestic and international missions for rotary-wing, UAV and fixed-wing platforms. Advanced Scout Surveillance System (LRAS3). The M2A3 Bradley Fighting Vehicles of the 4th ID have the Improved Bradley Acquisition System at the gunner’s station and the Commander’s Independent Viewer in the vehicle command station. The M1A2 SEP uses Raytheon’s Commander’s Independent Thermal Viewer for “hunter/killer” tactics. Raytheon Vision Systems in Santa Barbara, Calif., is a key supplier of our sensors’ detector, the Standard Advanced Dewar Assembly (SADA) II. The SADA is a 480 x 4 HgCdTe focal plane array (FPA) integrated with a one-watt linear cooler. In addition, Raytheon provides thousands of thermal weapon sights (TWS) mounted on the weapons of individual soldiers. The TWS family consists of three rugged sights providing long- (2.5 km), medium- (1.5 km) and short-range (600 m) target recognition matched to the capability of the individual and crew-served weapons. The TWS sights use two Raytheon detector technologies: scanned medium-wave infrared detectors are used in the medium- and long-range sights, and uncooled staring long-wave infrared 320 x 240 FPAs are used for the short-range sight. Each TWS mounts directly to the warfighter’s individual weapon, enabling day and night thermal targeting without affecting the soldier’s dismounted mobility. The high-fidelity imagery of second-generation FLIRS takes our warfighters from the days of “blob-ology” to reading facial AN/ASQ-228 ATFLIR Pod The AN/ASQ-228 ATFLIR pod is the most advanced infrared targeting system available for the F/A-18 aircraft. Combat-proven in operations Southern Watch (Iraq), Enduring Freedom and Iraqi Freedom, Raytheon’s AN/ASQ-228 ATFLIR is the Navy’s targeting pod program of record and the most technologically advanced system of its kind in the world. Its target detection range shows a fourfold improvement over previous systems, and laser designation is Photo Courtesy of U.S. Army ITAS 2nd-Generation FLIR – an integral component of U.S. ground forces expressions at greater than double the range of first-generation systems. This new level of performance has allowed traditionally anti-armor weapons systems, such as ITAS, to perform surveillance missions in OEF, and traditional surveillance sensors, such as LRAS3, to call for fire in OIF. Raytheon has received many accolades about the performance of our systems in OEF/OIF from all levels of the Army: “LRAS3 gave us the edge over the Iraqis … It allowed us to do our job better; it kept us from getting killed.” – Scout, 3rd ID, OIF “The FLIR and the TOW ITAS, in particular, was the hero of the battlefield.” – MG Petraeus, 101st Airborne, OIF “Lives were saved with TWS.” – BG J. Moran, PEO soldier We continue to “own the night.” Our warfighters are learning to use these systems more effectively with greater operability. Second-generation FLIR performance saves lives by providing standoff capability that allows for calls for fire, thus keeping our troops concealed. The ability of our warfighters to improvise new missions is a tribute to them and our EO sensor systems. • Hector Reyes hreyes@raytheon.com effective at altitudes up to 50,000 feet and at a slant range of greater than 30 miles. ATFLIR combines the mid-wave infrared targeting and navigation FLIRS, electro-optical sensor, laser rangefinder and target designator, and laser spot tracker into a single pod, freeing one air-to-air weapon station for other mission requirements. Compared to other targeting pods in production, the ATFLIR’s EO/IR imagery has three to five times greater clarity. • Robert Schaefer rdschaefer@raytheon.com 2005 ISSUE 1 7
