ASARS-2 provides extremely high resolution radar imagery from long ranges for the U-2 reconnaissance aircraft.
The ASARS-2 is the Advanced Synthetic Aperture Radar System for the high-altitude U.S. Air Force U-2 aircraft. It is a real-time, high-resolution reconnaissance system with all-weather, day-night, long-range mapping capabilities. ASARS-2 detects and accurately locates fixed and moving ground targets. It gathers detailed information, formats the data, and transmits high resolution images.
The civilian community has benefited from the ASARS-2's high resolution capability. It was used to map and assess damage from the floods along the Mississippi and Missouri rivers in 1993, the northern California floods in 1995, and the Northridge, California, earthquake in 1994.
In addition to supporting fielded ASARS-2 systems, Raytheon is currently delivering radar upgrades under the ASARS Improvement Program (AIP), which will further enhance ASARS-2 capabilities. ASARS-2 is the foundation for current production and development radars such as HISAR, Global Hawk, and the Airborne Reconnaissance Low-Magnification (ARL-M) Crazy Hawk.
